◆ computeFrustum()
| void Wizt::View::computeFrustum | ( | double | H, |
| double | W, | ||
| const Eagle::PhysicalSpace::Viewport & | theViewport | ||
| ) |
Compute the frustum from the current camera settings, near and far value, plus the given viewport and height/width information.
Modifies myFrustum, port, DeviceHeight and DeviceWidth.
References CameraSettings, myFrustum, Wizt::VCamera::Observer, and port.
Member Data Documentation
◆ myFrustum
| Eagle::PhysicalSpace::Frustum Wizt::View::myFrustum |
The view frustum related to the current CameraSettings.
It must be updated via calling its computeModelViewMatrix() function any time the CameraSettings are modified.
