Member Function Documentation

calculateProjectionMatrix()

virtual mat4 inviwo::OrthographicCamera::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.

getClipPosFromNormalizedDeviceCoords()

virtual vec4 inviwo::OrthographicCamera::getClipPosFromNormalizedDeviceCoords ( const vec3 & ndcCoords ) const

overridevirtual

Convert from normalized device coordinates (xyz in [-1 1]) to clip coordinates, where z value of -1 correspond to the near plane and 1 to the far plane. Coordinates outside of the [-1 1]^3 range will be clipped.

Parameters

ndcCoords

xyz clip-coordinates in [-1 1]^3, and the clip w-coordinate used for perspective division.

Returns
