示例1:
void IGLUShaderVariable::operator= ( float2 val )
{
// Check for a valid shader index
if ( m_varIdx < 0 ) return;
// Check for type mismatches
if ( m_isAttribute )
{
AssignmentToAttribute( "vec2" );
return;
}
if ( m_varType != GL_FLOAT_VEC2 && m_varType != GL_DOUBLE_VEC2 )
TypeMismatch( "vec2" );
// Ensure this program is currently bound, or setting shader values fails!
m_parent->PushProgram();
// For types of variable that can be assigned from our input value, assign them here
if ( m_varType == GL_FLOAT_VEC2 )
glUniform2fv( m_varIdx, 1, val.GetConstDataPtr() );
if ( m_varType == GL_DOUBLE_VEC2 )
glUniform2d( m_varIdx, val.X(), val.Y() );
// We have a short "program stack" so make sure to pop off.
m_parent->PopProgram();
}示例2: GenerateRay
float PerspectiveCamera::GenerateRay( const float2& rasterSample, const float2& lensSample, Ray* ray )
{
float3 ptRaster(rasterSample.X(), rasterSample.Y(), 0.0f);
float3 ptCamera = TransformCoord(ptRaster, mRasterToCamera);
ray->tMin = 0.0f;
ray->tMax = Mathf::INFINITY;
ray->Origin = Transform(float3(0,0,0), mCameraToWorld);
ray->Direction = Normalize(TransformDirection(ptCamera, mCameraToWorld));
return 1.0f;
}
