Hi guys, A quick little question. In the Object3D code, there are several matrixes. And as fair as I know, this is their function (correct me if i'm wrong)
transform.matrix3D -> The object's relative transform matrix, containing the position and rotation etc... _sceneMatrix3D -> The object's absolute transform matrix, "" _viewMatrix3D -> reference to Camera3D's matrix?? I want to know this, because in the project() function, it checks the cachedViewMatrix3D (The last known matrix/ the matrix of the previous frame) Then it compares the _viewMatrix3D to the _cachedViewMatrix3D, if so, it sets _scene.isDirty to true. _scene.isDirty is also set to true when the object's position is changed, and when a Mesh Material changed, etc... So the question (which turns out not to be a quick little question) is what the _viewMatrix3D represents. -Declan
