示例1: initPointCloud

private void initPointCloud() {
PGL pgl = ((PGraphicsOpenGL) parentApplet.g).pgl;
// TODO: lookt at the shaders...
myShader = parentApplet.loadShader(PointCloud.class.getResource("points.frag").toString(),
PointCloud.class.getResource("points.vert").toString());
myShader.bind();
shaderProgram = myShader.glProgram;
vertLoc = pgl.getAttribLocation(shaderProgram, "vertex");
colorsLoc = pgl.getAttribLocation(shaderProgram, "color");
transformLoc = pgl.getUniformLocation(shaderProgram, "transform");
myShader.unbind();
// System.out.println("Shader program " + shaderProgram + " vertex loc " + vertLoc + " transform loc " + transformLoc + " colors " + colorsLoc);
// Allocate the buffer in central memory (native), then java, then OpenGL
// Native memory
int byteSize = nbPoints * 4 * 4; // 4 : SizeOf Float -> ? SIZEOF_FLOAT
verticesNative = ByteBuffer.allocateDirect(byteSize).order(ByteOrder.nativeOrder()).
asFloatBuffer();

// Java memory
verticesJava = new float[nbPoints * 4];
colorsJava = new int[nbPoints];
// System.out.println("Buffer vertex object: " + glVertBuff);
// unbind the buffer.
pgl.bindBuffer(PGL.ARRAY_BUFFER, 0);
// Generate a buffer color data and color.
IntBuffer intBuffer = IntBuffer.allocate(2);
pgl.genBuffers(2, intBuffer);
