WebOpenGL doesn't explicitly define neither camera object nor a specific matrix for camera transformation. Instead, OpenGL transforms the entire scene inversely to the eye space, where a fixed camera is at the origin (0,0,0) and always looking along -Z axis. Web1 de fev. de 2024 · The root cause of the problem is that OpenGL matrix operations postmultiply onto the matrix stack, thus causing transformations to occur in object space. To affect screen space transformations, you need to premultiply. OpenGL doesn't provide a mode switch for the order of matrix multiplication, so you need to premultiply by hand.

In order to invert a rotation by unit quaternion q followed by a translation v, you apply a rotation by unit quaternion q' followed by a translation v' where: q' = ~q (conjugate of q, ie. inverse of rotation q) v' = -~q v q (transform of -v by the inverse of rotation q) If you only do translations and rotations, it is ...
