Constructor Detail

FragmentProgramState

public FragmentProgramState()

setEnvParameter sets an environmental fragment program parameter that is accessable by all fragment programs in memory.

Method Detail

setParameter

public void setParameter(float[] param,
                         int paramID)

setParameter sets a parameter for this fragment program.

Parameters:

paramID - identity number of the parameter, ranging from 0 to 23

param - four-element array of floating point numbers

isSupported

public abstract boolean isSupported()

isSupported determines if the ARB_fragment_program extension is supported by current graphics configuration.

Returns:

if ARB fragment programs are supported

getType

public int getType()

Description copied from class: RenderState

Defined by the subclass, this returns an int identifying the renderstate. For example, RS_CULL or RS_TEXTURE.

Specified by:

getType in class RenderState

Returns:

com.jme.scene.state.RenderState.RS_FRAGMENT_PROGRAM

See Also:

RenderState.getType()

load

public abstract void load(java.net.URL file)

load loads the fragment program from the specified file. The program must be in ASCII format. We delegate the loading to each implementation because we do not know in what format the underlying API wants the data.

Parameters:

file - text file containing the fragment program
