  1. [SOLVED] Node 3D to NDC coordinates

    Hi, I need the 2D screen Position of a 3D Node transformation. Can you write me a short code example with unigine matrices form the Player and Node and perspective division to get the NDC coordinates? auto proj = m_player->getProjection(); auto view = m_player->getTransform(); auto obj = instance->second->getNode()->getTransform(); auto projectedPosition = Unigine::Math::Mat4(proj)*view*obj*Unigine::Math::Vec4(0.0, 0.0, 0.0, 1.0); projectedPosition /= glm::abs(projectedPosition.w); x = (projectedPosition.x+1.0f)*0.5f * m_ungineAppHandle->getWidth(); y = (
  2. [SOLVED] Orthographic camera

    Hello everyone, I`m having a bit of a problem setting up a proper orthographic camera with C++ API in my projects. It seems that there is no way for me to change a camera projection without creating my own mat4 and passing it as an argument to setProjection to the class camera. Is there any other way around to acomplish this task without going in depth with matrix conversations?
