Class SimpleShaderProgram

java.lang.Object

org.artoolkitx.arx.arxj.rendering.ShaderProgram

org.artoolkitx.arx.arxj.rendering.shader_impl.SimpleShaderProgram

public class SimpleShaderProgram
extends ShaderProgram

The shader program links together the vertex shader and the fragment shader and compiles them. It also is responsible for binding the attributes. Attributes can be used to pass in values to the shader during runtime.
Finally it renders the given geometry.

SimpleShaderProgram

public SimpleShaderProgram(OpenGLShader vertexShader,
                           OpenGLShader fragmentShader)

Method Detail

bindAttributes

protected void bindAttributes()

Specified by:

bindAttributes in class ShaderProgram

getProjectionMatrixHandle

public int getProjectionMatrixHandle()

Specified by:

getProjectionMatrixHandle in class ShaderProgram

getModelViewMatrixHandle

public int getModelViewMatrixHandle()

Specified by:

getModelViewMatrixHandle in class ShaderProgram

getPositionHandle

public int getPositionHandle()

render

public void render(java.nio.FloatBuffer vertexBuffer,
                   java.nio.FloatBuffer colorBuffer,
                   java.nio.ByteBuffer indexBuffer)

There are several render methods available from the base class. In this case we override the ShaderProgram.render(FloatBuffer, FloatBuffer, ByteBuffer) one. Although we never use the index ByteBuffer. We pass in the vertex and color information from the org.artoolkit.arx.arxj.rendering.shader_impl.Line object.

Overrides:

render in class ShaderProgram

Parameters:

vertexBuffer - Contains the position information as two vertexes. Start and end of the line to draw

colorBuffer - Contains the color of the line

indexBuffer - TODO
