Method Detail

isSupported

public boolean isSupported()

Determines if the current OpenGL context supports the GL_ARB_shader_objects extension.

Specified by:

isSupported in class GLSLShaderObjectsState

Returns:

if ARB shader objects are supported

com.jme.scene.state.ShaderObjectsState#isSupported()

relinkProgram

public void relinkProgram()

relinkProgram instructs openGL to relink the associated program. This should be used after setting ShaderAttributes.

Specified by:

relinkProgram in class GLSLShaderObjectsState

load

public void load(java.net.URL vert,
                 java.net.URL frag)

Loads the shader object.

Specified by:

load in class GLSLShaderObjectsState

Parameters:

vert - text file containing the vertex shader object

frag - text file containing the fragment shader object

See Also:

com.jme.scene.state.ShaderObjectsState#load(java.net.URL, java.net.URL)

apply

public void apply()

Applies those shader objects to the current scene. Checks if the GL_ARB_shader_objects extension is supported before attempting to enable those objects.

Specified by:

apply in class RenderState
