public abstract class SoUniformShaderParameter extends SoShaderParameter
SoShaderParameter1i
, are derived.
These nodes allow users to provide uniform parameters to a given shader object, e.g. SoFragmentShader
.
Uniform shader parameter nodes are usually added to the shader object's
parameter field to affect only that specific shader program. They can also be inserted in the scene graph after an SoShaderProgram
. In this case they affect whatever shader program is in effect when a shape is rendered.
Each parameter is defined by the following properties:
See the base class SoShaderParameter
to get information about how to specify the name and/or identifier of a parameter.
The following examples show how to set a parameter named "scale" in two different ways.
In this case, a uniform parameter is added to a specific shader program:
SoShaderParameter3f parameterNode = new SoShaderParameter3f(); parameterNode.name.setValue( "scale" ); parameterNode.value.setValue(2, 2, 2); SoVertexShader vertexShader = new SoVertexShader(); vertexShader.sourceProgram.setValue( "filename.glsl" ); vertexShader.parameter.set1Value( 0, parameterNode ); // Affects this shader SoShaderProgram shaderProgram = new SoShaderProgram(); shaderProgram.shaderObject.set1Value( 0, vertexShader ); root.addChild(shaderProgram);
This code sets a uniform parameter with an SoShaderParameter
included in the scene graph:
SoShaderParameter3f parameterNode = new SoShaderParameter3f(); parameterNode.name.setValue( "scale" ); parameterNode.value.setValue(2, 2, 2); root.addChild( parameterNode ); // Affects all subsequent shaders SoVertexShader vertexShader = new SoVertexShader(); vertexShader.sourceProgram.setValue( "filename.glsl" ); SoShaderProgram shaderProgram = new SoShaderProgram(); shaderProgram.shaderObject.set1Value( 0, vertexShader ); root.addChild(shaderProgram);
