Class ShaderProgram

java.lang.Object

gov.nasa.worldwind.render.ShaderProgram

All Implemented Interfaces:

RenderResource

Direct Known Subclasses:

BasicShaderProgram, SurfaceTextureProgram

public class ShaderProgram
extends java.lang.Object
implements RenderResource

Represents an OpenGL shading language (GLSL) shader program and provides methods for identifying and accessing shader variables. Shader programs are configured by calling setProgramSources to specify the the GLSL vertex shader and fragment shader source code, then made current by calling useProgram.
