Class PShapeOpenGL

  • All Implemented Interfaces:
    PConstants 

    public class PShapeOpenGL
extends PShape
    This class holds a 3D model composed of vertices, normals, colors (per vertex) and texture coordinates (also per vertex). All this data is stored in Vertex Buffer Objects (VBO) in GPU memory for very fast access. OBJ loading implemented using code from Saito's OBJLoader library: http://code.google.com/p/saitoobjloader/ and OBJReader from Ahmet Kizilay http://www.openprocessing.org/visuals/?visualID=191 By Andres Colubri Other formats to consider: AMF: http://en.wikipedia.org/wiki/Additive_Manufacturing_File_Format STL: http://en.wikipedia.org/wiki/STL_(file_format) OFF: http://people.sc.fsu.edu/~jburkardt/data/off/off.html(file_format) DXF: http://en.wikipedia.org/wiki/AutoCAD_DXF

      • translate

        public void translate(float tx,
 float ty)
        Description copied from class: PShape
        ( begin auto-generated from PShape_translate.xml ) Specifies an amount to displace the shape. The x parameter specifies left/right translation, the y parameter specifies up/down translation, and the z parameter specifies translations toward/away from the screen. Subsequent calls to the method accumulates the effect. For example, calling translate(50, 0) and then translate(20, 0) is the same as translate(70, 0). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.

        Using this method with the z parameter requires using the P3D parameter in combination with size. ( end auto-generated )
        Overrides:
        translate in class PShape
        Parameters:
        tx - left/right translation
        ty - up/down translation
        See Also:
        PShape.rotate(float), PShape.scale(float), PShape.resetMatrix()

      • translate

        public void translate(float tx,

        Overrides:
        translate in class PShape
        tz - forward/back translation

      • rotate

        public void rotate(float angle)
        Description copied from class: PShape
        ( begin auto-generated from PShape_rotate.xml ) Rotates a shape the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method.

        Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the method accumulates the effect. For example, calling rotate(HALF_PI) and then rotate(HALF_PI) is the same as rotate(PI). This transformation is applied directly to the shape, it's not refreshed each time draw() is run. ( end auto-generated )
        Overrides:
        rotate in class PShape
        Parameters:
        angle - angle of rotation specified in radians
        See Also:

      • rotateX

        public void rotateX(float angle)
        Description copied from class: PShape
        ( begin auto-generated from PShape_rotateX.xml ) Rotates a shape around the x-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method.

        Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Subsequent calls to the method accumulates the effect. For example, calling rotateX(HALF_PI) and then rotateX(HALF_PI) is the same as rotateX(PI). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.

        This method requires a 3D renderer. You need to use P3D as a third parameter for the size() function as shown in the example above. ( end auto-generated )
        Overrides:
        rotateX in class PShape
        Parameters:
        angle - angle of rotation specified in radians

      • rotateY

        public void rotateY(float angle)
        Description copied from class: PShape
        ( begin auto-generated from PShape_rotateY.xml ) Rotates a shape around the y-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method.

        Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Subsequent calls to the method accumulates the effect.

      • rotateZ

        public void rotateZ(float angle)
        Description copied from class: PShape
        ( begin auto-generated from PShape_rotateZ.xml ) Rotates a shape around the z-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() method.

        Shapes are always rotated around the upper-left corner of their bounding box. Positive numbers rotate objects in a clockwise direction. Subsequent calls to the method accumulates the effect. For example, calling rotateZ(HALF_PI) and then rotateZ(HALF_PI) is the same as rotateZ(PI). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.

      • scale

        public void scale(float s)
        Description copied from class: PShape
        ( begin auto-generated from PShape_scale.xml ) Increases or decreases the size of a shape by expanding and contracting vertices. Shapes always scale from the relative origin of their bounding box. Scale values are specified as decimal percentages. For example, the method call scale(2.0) increases the dimension of a shape by 200%. Subsequent calls to the method multiply the effect. For example, calling scale(2.0) and then scale(1.5) is the same as scale(3.0). This transformation is applied directly to the shape, it's not refreshed each time draw() is run.

        Using this method with the z parameter requires using the P3D parameter in combination with size. ( end auto-generated )

        Parameters:
