{
Matrix4 m;
GLfloat det = Determinant();
if(fabs(det) < 0.000001f) return(m);
for(GLuint c=0; c<4; c++)

}示例2:
void NodeIntersector<real>::TransformIntersectionToGlobalCoordinates( const CoreLib::Node<real>* node, Intersection<real>& ioIntersection )
{
// newPosition = M * position
// newNormal = M^{-T} * normal
const Matrix4<real>& localToGlobal = node->GetLocalToGlobal();
Matrix4<real> localToGlobalForNormals = node->GetGlobalToLocal();
localToGlobalForNormals.Transpose();
ioIntersection.SetPosition( localToGlobal * ioIntersection.GetPosition() );
ioIntersection.SetNormal( localToGlobalForNormals ^ ioIntersection.GetNormal() );
}示例3: SetParameter
void SpriteShader::SetParameter(const std::string ¶meterName, const Matrix4 &value)
{
if(pimpl->uniforms.find(parameterName) == pimpl->uniforms.end())
throw std::runtime_error("Couldn't find the named SpriteEffect parameter: " + parameterName);

if(uniformData.type != GL_FLOAT_MAT4)
throw std::runtime_error("Type mismatch for named SpriteEffect paramater: " + parameterName);
glUniformMatrix4fv(uniformData.location, 1, GL_FALSE, value.Transpose());
}示例4: GetCameraRotationMatrix
Matrix4 Camera3D::GetCameraViewMatrix(){
//get transform matrix
Matrix4 cameraTransformMatrix;
cameraTransformMatrix.Translate(m_position);
cameraTransformMatrix.m_translation.x *= -1.0f; //stopgap fix for -zUP issue
cameraTransformMatrix.m_translation.z *= -1.0f; //stopgap fix for -zUP issue
Matrix4 viewMatrix = /* GetCameraRotationMatrix() * */ cameraTransformMatrix * GetCameraRotationMatrix();
//R*T = rotate around origin, movement correct
//T*R = rotate correct, absolute movement
viewMatrix.Transpose();
//the movement is absolute regardless of rotation for whatever reason...
return viewMatrix;
