```c++
glm::mat4 VPmatrix = projection * view;
glm::vec4 screenPos = VPmatrix * glm::vec4(instance->pos, 1.0f);
screenPos.x /= screenPos.w;
screenPos.y /= screenPos.w;
screenPos.x = (screenPos.x + 1.0f) / 2.0f;
screenPos.y = (screenPos.y + 1.0f) / 2.0f;
screenPos.x *= viewportWidth;
screenPos.y *= viewportHeight;
screenPos.y = (screenPos.y + 1.0f) / 2.0f;
