Member Function Documentation

◆ calculateProjectionMatrix()

virtual mat4 inviwo::SkewedPerspectiveCamera::calculateProjectionMatrix ( ) const

overrideprotectedvirtual

Calculate and return the projection matrix for the camera.

Implement this function to provide your own projection computation functionality. For example orthogonal or perspective projection. This function will be called when the projection matrix is invalid.
