示例1: draw
void CameraPathControls::draw(const mat4& projection, const mat4 views[],
const vec3& lightPositionWorld,
const int& selectedControlPoint,
float deltaT) const {
/// Common drawing.
predraw();
/// Update the model matrix.
static float angle = 1.0f;
angle += deltaT * 1.0f;
mat4 rotationMatrix = mat4::Identity();
rotationMatrix(0,0) = +std::cos(angle);
rotationMatrix(0,1) = -std::sin(angle);
rotationMatrix(1,0) = +std::sin(angle);
rotationMatrix(1,1) = +std::cos(angle);
/// Update the content of the uniforms.
glUniformMatrix4fv( _projectionID, 1, GL_FALSE, projection.data());
glUniformMatrix4fv( _viewID, 1, GL_FALSE, views[0].data());
glUniform3fv(_lightPositionWorldID, 1, lightPositionWorld.data());
glUniform1i( _selectedControlPointID, selectedControlPoint);
glUniformMatrix4fv(_rotationMatrixID, 1, GL_FALSE, rotationMatrix.data());
/// Render from camera point of view to 'normal' FBOs.
glBindFramebuffer(GL_FRAMEBUFFER, framebufferIDs["controllerView"]);
