proj | Source projection matrix. |
renderIntoTexture | Will this projection be used for rendering into a RenderTexture? |
Matrix4x4 Adjusted projection matrix for the current graphics API.
Compute GPU projection matrix from camera's projection matrix.
In Unity, projection matrices follow OpenGL convention. However on some platforms they
have to be transformed a bit to match the native API requirements. Use this function
to calculate how the final projection matrix will be like. The value will match what
comes as UNITY_MATRIX_P
matrix in a shader.
The renderIntoTexture
value should be set to true if you intend to render into a
RenderTexture with this projection matrix. On some platforms it affects how
the final matrix will look like.
