Constructor & Destructor Documentation

G3D::VertexAndPixelShader::GPUShader::~GPUShader ( )

Deletes the underlying glShaderObject.

Between GL's reference counting and G3D's reference counting, an underlying object can never be deleted while in use.

Member Function Documentation

void G3D::VertexAndPixelShader::GPUShader::compile ( ) [protected]

Returns true on success.

Called from init.

bool G3D::VertexAndPixelShader::GPUShader::fixedFunction ( ) const [inline]

GLhandleARB G3D::VertexAndPixelShader::GPUShader::glShaderObject ( ) const [inline]

Returns the underlying OpenGL shader object for this shader.

GLenum G3D::VertexAndPixelShader::GPUShader::glShaderType ( ) const [inline]

Shader type, e.g.

GL_VERTEX_SHADER_ARB

void G3D::VertexAndPixelShader::GPUShader::init	(	const std::string &	name,
		const std::string &	code,
		bool	fromFile,
		bool	debug,
		GLenum	glType,
		const std::string &	type,
		UseG3DUniforms	u
	)

static GPUShader* G3D::VertexAndPixelShader::GPUShader::init	(	GPUShader *	shader,
		bool	debug
	)			`[static, protected]`

Initialize a shader object and returns object.

Called from subclass create methods.

const std::string& G3D::VertexAndPixelShader::GPUShader::messages ( ) const [inline]

Why compilation failed, or any compiler warnings if it succeeded.

bool G3D::VertexAndPixelShader::GPUShader::ok ( ) const [inline]

Returns true if compilation and loading succeeded.

If they failed, check the message string.

void G3D::VertexAndPixelShader::GPUShader::replaceG3DSize	(	std::string &	code,
		std::string &	uniformString
	)			`[protected]`

Replaces all instances of "g3d_sampler2DSize(name)" with " (g3d_sz2D_name.xy)" and.

"g3d_sampler2DInvSize(name)" with " (g3d_sz2D_name.zw)"

Note that both replacements will leave column numbers the same in error messages. The () wrapper ensures that .xy fields are accessible using normal syntax off the result; it is the same as the standard practice of wrapping macros in parentheses.

and adds "uniform vec4 g3d_sz2D_name;" to the uniform string.

Called from init.
