com.marginallyclever.ro3.shader.ShaderProgram

All Implemented Interfaces:

OpenGL3Resource

public class ShaderProgram
extends Object
implements OpenGL3Resource

ShaderProgram is a wrapper for shader programs made of several Shaders. It also provides a simple interface for setting uniforms.

Method Details

showProgramError

public void showProgramError(com.jogamp.opengl.GL3 gl,
 String message)

use

public void use(com.jogamp.opengl.GL3 gl)

unload

public void unload(com.jogamp.opengl.GL3 gl)

Specified by:

unload in interface OpenGL3Resource

getProgramId

public int getProgramId()

getUniformLocation

public int getUniformLocation(com.jogamp.opengl.GL3 gl,
 String name)

set1f

public void set1f(com.jogamp.opengl.GL3 gl,
 String name,
 float v0)

set2f

public void set2f(com.jogamp.opengl.GL3 gl,
 String name,
 float v0,
 float v1)

set3f

public void set3f(com.jogamp.opengl.GL3 gl,
 String name,
 float v0,
 float v1,
 float v2)

set4f

public void set4f(com.jogamp.opengl.GL3 gl,
 String name,
 float v0,
 float v1,
 float v2,
 float v3)

setVector3d

public void setVector3d(com.jogamp.opengl.GL3 gl,
 String name,
 javax.vecmath.Vector3d value)

setMatrix4d

public void setMatrix4d(com.jogamp.opengl.GL3 gl,
 String name,
 javax.vecmath.Matrix4d value)

Set a matrix in the shader. Java uses column-major order, where OpenGL and DirectX use row-major order. Thus the thurd parameter is true to make the video card transpose the matrix from row-major to column-major.

Parameters:

gl - the viewport context

name - the name of the uniform variable

value - the matrix to set
