TextureShaderProgram
public TextureShaderProgram()

activate
public void activate() Activates the shader program. This method is normally called for each renderable, or when the shader program is switched to. Specified By: activate in ShaderProgram

cleanup
public void cleanup() Removes any unused state created by this shader program from the rendering context. This method is normally called when the shader program is no longer needed for the current frame. Note that the program may be needed for the next frame, so it should not deallocate its global resources. Specified By: cleanup in ShaderProgram

compile
public void compile() Compiles the shader program and sets up variables and handles. Specified By: compile in ShaderProgram

compile

protected void compile(
    String vertexShaderCode,
    String fragmentShaderCode
)

Compiles this shader program with given vertex and fragment shader codes.

Parameters:

vertexShaderCode	Vertex shader code
fragmentShaderCode	Fragment shader code

destroy
public void destroy() Destroys the shader program and frees all allocated resources. The shader will not be used after this method, unless the `compile()` method is called again. Specified By: destroy in ShaderProgram

feed
public void feed( float[] mat ) Feeds a transformation matrix to this shader program. This matrix is also multiplied by the projection matrix and can be directly used to draw elements. Specified By: feed in ShaderProgram

feed
public void feed( FloatBuffer vertexBuffer ) Feeds a vertex strip for the element to be drawn on the screen. Specified By: feed in ShaderProgram

feed
public void feed( float r, float g, float b, float a ) Feeds a color component to this shader program. All shader programs in this framework are expected to accept one color component. But how they use this component is not defined. Specified By: feed in ShaderProgram

feed

public void feed(
    int textureDataHandle
)

Feeds a texture to this shader program.

Parameters:

textureDataHandle

Texture data handle

feedTexCoords

public void feedTexCoords(
    FloatBuffer buffer
)

Feeds texture a coordinate buffer to this shader program.

Parameters:

buffer

Texture coordinate buffer

getDefaultTextureBuffer
public static FloatBuffer getDefaultTextureBuffer() Gets the default texture coordinates buffer, which includes the whole area of the texture image. Returns: Default texture coordinates
