- * Simplified method to open a Java InputStream.

- * This method is useful if you want to use the facilities provided
- * by PApplet to easily open things from the data folder or from a URL,
- * but want an InputStream object so that you can use other Java
- * methods to take more control of how the stream is read.
- *
- * If the requested item doesn't exist, null is returned.
- * (Prior to 0096, die() would be called, killing the applet)
- *
- * For 0096, the "data" folder is exported intact with subfolders,
- * and openStream() properly handles subdirectories from the data folder
- *
- * If not online, this will also check to see if the user is asking
- * for a file whose name isn't properly capitalized. This helps prevent
- * issues when a sketch is exported to the web, where case sensitivity
- * matters, as opposed to Windows and the Mac OS default where
- * case sensitivity is preserved but ignored.
- *
- * It is strongly recommended that libraries use this method to open
- * data files, so that the loading sequence is handled in the same way
- * as functions like loadBytes(), loadImage(), etc.
- *
- * The filename passed in can be:
- *
- * In this method, the data path is defined not as the applet's actual
- * data path, but a folder titled "data" in the sketch's working
- * directory. This is because in an application, the "data" folder is
- * exported as part of the jar file, and it's not as though you're gonna
- * write into the jar file itself. If you need to get things out of
- * the jar file, you should use openStream().

+ * This method is useful if you want to use the facilities provided
+ * by PApplet to easily open things from the data folder or from a URL,
+ * but want an InputStream object so that you can use other Java
+ * methods to take more control of how the stream is read.
+ *
+ * If the requested item doesn't exist, null is returned.
+ * (Prior to 0096, die() would be called, killing the applet)
+ *
+ * For 0096, the "data" folder is exported intact with subfolders,
+ * and openStream() properly handles subdirectories from the data folder
+ *
+ * If not online, this will also check to see if the user is asking
+ * for a file whose name isn't properly capitalized. This helps prevent
+ * issues when a sketch is exported to the web, where case sensitivity
+ * matters, as opposed to Windows and the Mac OS default where
+ * case sensitivity is preserved but ignored.
+ *
+ * It is strongly recommended that libraries use this method to open
+ * data files, so that the loading sequence is handled in the same way
+ * as functions like loadBytes(), loadImage(), etc.
+ *
+ * The filename passed in can be:
+ *
+ * In this method, the data path is defined not as the applet's actual
+ * data path, but a folder titled "data" in the sketch's working
+ * directory. This is because in an application, the "data" folder is
+ * exported as part of the jar file, and it's not as though you're gonna
+ * write into the jar file itself. If you need to get things out of
+ * the jar file, you should use openStream().

- * Differences between beginShape() and line() and point() methods.
- *
- * beginShape() is intended to be more flexible at the expense of being
- * a little more complicated to use. it handles more complicated shapes
- * that can consist of many connected lines (so you get joins) or lines
- * mixed with curves.
- *
- * The line() and point() command are for the far more common cases
- * (particularly for our audience) that simply need to draw a line
- * or a point on the screen.
- *
- * From the code side of things, line() may or may not call beginShape()
- * to do the drawing. In the beta code, they do, but in the alpha code,
- * they did not. they might be implemented one way or the other depending
- * on tradeoffs of runtime efficiency vs. implementation efficiency &mdash
- * meaning the speed that things run at vs. the speed it takes me to write
- * the code and maintain it. for beta, the latter is most important so

- *
- * Processing camera behavior:
- *
- * Camera behavior can be split into two separate components, camera
- * transformation, and projection. The transformation corresponds to the
- * physical location, orientation, and scale of the camera. In a physical
- * camera metaphor, this is what can manipulated by handling the camera
- * body (with the exception of scale, which doesn't really have a physcial
- * analog). The projection corresponds to what can be changed by
- * manipulating the lens.
- *
- * We maintain separate matrices to represent the camera transform and
- * projection. An important distinction between the two is that the camera
- * transform should be invertible, where the projection matrix should not,
- * since it serves to map three dimensions to two. It is possible to bake
- * the two matrices into a single one just by multiplying them together,
- * but it isn't a good idea, since lighting, z-ordering, and z-buffering
- * all demand a true camera z coordinate after modelview and camera
- * transforms have been applied but before projection. If the camera
- * transform and projection are combined there is no way to recover a
- * good camera-space z-coordinate from a model coordinate.
- *
- * Fortunately, there are no functions that manipulate both camera
- * transformation and projection.
- *
- * camera() sets the camera position, orientation, and center of the scene.
- * It replaces the camera transform with a new one. This is different from
- * gluLookAt(), but I think the only reason that GLU's lookat doesn't fully
- * replace the camera matrix with the new one, but instead multiplies it,
- * is that GL doesn't enforce the separation of camera transform and
- * projection, so it wouldn't be safe (you'd probably stomp your projection).
- *
- * The transformation functions are the same ones used to manipulate the
- * modelview matrix (scale, translate, rotate, etc.). But they are bracketed
- * with beginCamera(), endCamera() to indicate that they should apply
- * (in inverse), to the camera transformation matrix.
- *
- * This differs considerably from camera transformation in OpenGL.
- * OpenGL only lets you say, apply everything from here out to the
- * projection or modelview matrix. This makes it very hard to treat camera
- * manipulation as if it were a physical camera. Imagine that you want to
- * move your camera 100 units forward. In OpenGL, you need to apply the
- * inverse of that transformation or else you'll move your scene 100 units
- * forward--whether or not you've specified modelview or projection matrix.
- * Remember they're just multiplied by model coods one after another.
- * So in order to treat a camera like a physical camera, it is necessary
- * to pre-apply inverse transforms to a matrix that will be applied to model
- * coordinates. OpenGL provides nothing of this sort, but Processing does!
- * This is the camera transform matrix.

+ * Processing camera behavior:
+ *
+ * Camera behavior can be split into two separate components, camera
+ * transformation, and projection. The transformation corresponds to the
+ * physical location, orientation, and scale of the camera. In a physical
+ * camera metaphor, this is what can manipulated by handling the camera
+ * body (with the exception of scale, which doesn't really have a physcial
+ * analog). The projection corresponds to what can be changed by
+ * manipulating the lens.
+ *
+ * We maintain separate matrices to represent the camera transform and
+ * projection. An important distinction between the two is that the camera
+ * transform should be invertible, where the projection matrix should not,
+ * since it serves to map three dimensions to two. It is possible to bake
+ * the two matrices into a single one just by multiplying them together,
+ * but it isn't a good idea, since lighting, z-ordering, and z-buffering
+ * all demand a true camera z coordinate after modelview and camera
+ * transforms have been applied but before projection. If the camera
+ * transform and projection are combined there is no way to recover a
+ * good camera-space z-coordinate from a model coordinate.
+ *
+ * Fortunately, there are no functions that manipulate both camera
+ * transformation and projection.
+ *
+ * camera() sets the camera position, orientation, and center of the scene.
+ * It replaces the camera transform with a new one. This is different from
+ * gluLookAt(), but I think the only reason that GLU's lookat doesn't fully
+ * replace the camera matrix with the new one, but instead multiplies it,
+ * is that GL doesn't enforce the separation of camera transform and
+ * projection, so it wouldn't be safe (you'd probably stomp your projection).
+ *
+ * The transformation functions are the same ones used to manipulate the
+ * modelview matrix (scale, translate, rotate, etc.). But they are bracketed
+ * with beginCamera(), endCamera() to indicate that they should apply
+ * (in inverse), to the camera transformation matrix.
+ *
+ * This differs considerably from camera transformation in OpenGL.
+ * OpenGL only lets you say, apply everything from here out to the
+ * projection or modelview matrix. This makes it very hard to treat camera
+ * manipulation as if it were a physical camera. Imagine that you want to
+ * move your camera 100 units forward. In OpenGL, you need to apply the
+ * inverse of that transformation or else you'll move your scene 100 units
+ * forward--whether or not you've specified modelview or projection matrix.
+ * Remember they're just multiplied by model coods one after another.
+ * So in order to treat a camera like a physical camera, it is necessary
+ * to pre-apply inverse transforms to a matrix that will be applied to model
+ * coordinates. OpenGL provides nothing of this sort, but Processing does!
+ * This is the camera transform matrix.

- *
- * The Lighting Skinny:
- *
- * The way lighting works is complicated enough that it's worth
- * producing a document to describe it. Lighting calculations proceed
- * pretty much exactly as described in the OpenGL red book.
- *
- * Light-affecting material properties:
- *
- * AMBIENT COLOR
- * - multiplies by light's ambient component
- * - for believability this should match diffuse color
- *
- * DIFFUSE COLOR
- * - multiplies by light's diffuse component
- *
- * SPECULAR COLOR
- * - multiplies by light's specular component
- * - usually less colored than diffuse/ambient
- *
- * SHININESS
- * - the concentration of specular effect
- * - this should be set pretty high (20-50) to see really
- * noticeable specularity
- *
- * EMISSIVE COLOR
- * - constant additive color effect
- *
- * Light types:
- *
- * AMBIENT
- * - one color
- * - no specular color
- * - no direction
- * - may have falloff (constant, linear, and quadratic)
- * - may have position (which matters in non-constant falloff case)
- * - multiplies by a material's ambient reflection
- *
- * DIRECTIONAL
- * - has diffuse color
- * - has specular color
- * - has direction
- * - no position
- * - no falloff
- * - multiplies by a material's diffuse and specular reflections
- *
- * POINT
- * - has diffuse color
- * - has specular color
- * - has position
- * - no direction
- * - may have falloff (constant, linear, and quadratic)
- * - multiplies by a material's diffuse and specular reflections
- *
- * SPOT
- * - has diffuse color
- * - has specular color
- * - has position
- * - has direction
- * - has cone angle (set to half the total cone angle)
- * - has concentration value
- * - may have falloff (constant, linear, and quadratic)
- * - multiplies by a material's diffuse and specular reflections
- *
- * Normal modes:
- *
- * All of the primitives (rect, box, sphere, etc.) have their normals
- * set nicely. During beginShape/endShape normals can be set by the user.
- *
- * AUTO-NORMAL
- * - if no normal is set during the shape, we are in auto-normal mode
- * - auto-normal calculates one normal per triangle (face-normal mode)
- *
- * SHAPE-NORMAL
- * - if one normal is set during the shape, it will be used for
- * all vertices
- *
- * VERTEX-NORMAL
- * - if multiple normals are set, each normal applies to
- * subsequent vertices
- * - (except for the first one, which applies to previous
- * and subsequent vertices)
- *
- * Efficiency consequences:
- *
- * There is a major efficiency consequence of position-dependent
- * lighting calculations per vertex. (See below for determining
- * whether lighting is vertex position-dependent.) If there is no
- * position dependency then the only factors that affect the lighting
- * contribution per vertex are its colors and its normal.
- * There is a major efficiency win if
- *
- * 1) lighting is not position dependent
- * 2) we are in AUTO-NORMAL or SHAPE-NORMAL mode
- *
- * because then we can calculate one lighting contribution per shape
- * (SHAPE-NORMAL) or per triangle (AUTO-NORMAL) and simply multiply it
- * into the vertex colors. The converse is our worst-case performance when
- *
- * 1) lighting is position dependent
- * 2) we are in AUTO-NORMAL mode
- *
- * because then we must calculate lighting per-face * per-vertex.
- * Each vertex has a different lighting contribution per face in
- * which it appears. Yuck.
- *
- * Determining vertex position dependency:
- *
- * If any of the following factors are TRUE then lighting is
- * vertex position dependent:
- *
- * 1) Any lights uses non-constant falloff
- * 2) There are any point or spot lights
- * 3) There is a light with specular color AND there is a
- * material with specular color
- *
- * So worth noting is that default lighting (a no-falloff ambient
- * and a directional without specularity) is not position-dependent.
- * We should capitalize.

+ *
+ * The Lighting Skinny:
+ *
+ * The way lighting works is complicated enough that it's worth
+ * producing a document to describe it. Lighting calculations proceed
+ * pretty much exactly as described in the OpenGL red book.
+ *
+ * Light-affecting material properties:
+ *
+ * AMBIENT COLOR
+ * - multiplies by light's ambient component
+ * - for believability this should match diffuse color
+ *
+ * DIFFUSE COLOR
+ * - multiplies by light's diffuse component
+ *
+ * SPECULAR COLOR
+ * - multiplies by light's specular component
+ * - usually less colored than diffuse/ambient
+ *
+ * SHININESS
+ * - the concentration of specular effect
+ * - this should be set pretty high (20-50) to see really
+ * noticeable specularity
+ *
+ * EMISSIVE COLOR
+ * - constant additive color effect
+ *
+ * Light types:
+ *
+ * AMBIENT
+ * - one color
+ * - no specular color
+ * - no direction
+ * - may have falloff (constant, linear, and quadratic)
+ * - may have position (which matters in non-constant falloff case)
+ * - multiplies by a material's ambient reflection
+ *
+ * DIRECTIONAL
+ * - has diffuse color
+ * - has specular color
+ * - has direction
+ * - no position
+ * - no falloff
+ * - multiplies by a material's diffuse and specular reflections
+ *
+ * POINT
+ * - has diffuse color
+ * - has specular color
+ * - has position
+ * - no direction
+ * - may have falloff (constant, linear, and quadratic)
+ * - multiplies by a material's diffuse and specular reflections
+ *
+ * SPOT
+ * - has diffuse color
+ * - has specular color
+ * - has position
+ * - has direction
+ * - has cone angle (set to half the total cone angle)
+ * - has concentration value
+ * - may have falloff (constant, linear, and quadratic)
+ * - multiplies by a material's diffuse and specular reflections
+ *
+ * Normal modes:
+ *
+ * All of the primitives (rect, box, sphere, etc.) have their normals
+ * set nicely. During beginShape/endShape normals can be set by the user.
+ *
+ * AUTO-NORMAL
+ * - if no normal is set during the shape, we are in auto-normal mode
+ * - auto-normal calculates one normal per triangle (face-normal mode)
+ *
+ * SHAPE-NORMAL
+ * - if one normal is set during the shape, it will be used for
+ * all vertices
+ *
+ * VERTEX-NORMAL
+ * - if multiple normals are set, each normal applies to
+ * subsequent vertices
+ * - (except for the first one, which applies to previous
+ * and subsequent vertices)
+ *
+ * Efficiency consequences:
+ *
+ * There is a major efficiency consequence of position-dependent
+ * lighting calculations per vertex. (See below for determining
+ * whether lighting is vertex position-dependent.) If there is no
+ * position dependency then the only factors that affect the lighting
+ * contribution per vertex are its colors and its normal.
+ * There is a major efficiency win if
+ *
+ * 1) lighting is not position dependent
+ * 2) we are in AUTO-NORMAL or SHAPE-NORMAL mode
+ *
+ * because then we can calculate one lighting contribution per shape
+ * (SHAPE-NORMAL) or per triangle (AUTO-NORMAL) and simply multiply it
+ * into the vertex colors. The converse is our worst-case performance when
+ *
+ * 1) lighting is position dependent
+ * 2) we are in AUTO-NORMAL mode
+ *
+ * because then we must calculate lighting per-face * per-vertex.
+ * Each vertex has a different lighting contribution per face in
+ * which it appears. Yuck.
+ *
+ * Determining vertex position dependency:
+ *
+ * If any of the following factors are TRUE then lighting is
+ * vertex position dependent:
+ *
+ * 1) Any lights uses non-constant falloff
+ * 2) There are any point or spot lights
+ * 3) There is a light with specular color AND there is a
+ * material with specular color
+ *
+ * So worth noting is that default lighting (a no-falloff ambient
+ * and a directional without specularity) is not position-dependent.
+ * We should capitalize.
