Detailed Description

The ShaderPart node defines the source for a single object to be used by a ComposedShader node.

The source is not required to be a complete shader for all of the vertex/fragment processing.

The type field indicates whether this object shall be compiled as a vertex shader, fragment shader, or other future-defined shader type.

The shader source is read from the URL specified by the url field. When the url field contains no values ([]), this object instance is ignored. Shader source files shall be plain text encoded as specified for MIME type text/plain and interpreted according to the type field.

Member Function Documentation

GLhandleARB ShaderPart::compileShader (   )  [virtual]

Compile the shader using the shader_string field as text input. Returns a handle to the compiled shader or 0 if compiling failed.

virtual string H3D::ShaderPart::defaultXMLContainerField (   )  [inline, virtual]

Returns the default xml containerField attribute value. For this node it is "parts". Reimplemented from H3D::Node.

auto_ptr< SFShaderString > H3D::ShaderPart::shaderString

Internal field that contains the string loaded from file and to be used as input to the shader.

auto_ptr< SFString > H3D::ShaderPart::type

The type field indicates whether this object shall be compiled as a vertex shader, fragment shader, or other future-defined shader type. Valid values are "VERTEX" and "FRAGMENT". Access type: initializeOnly
