Function Documentation

LsgFrustum* LsgFrustum_create ( const Matrix projection,

const Matrix modelview

)

Allocate and initialize a view frustum.
Parameters:

projection The projection matrix

modelview The modelview matrix

Returns:
The view frustum as defined by projection and modelview

void LsgFrustum_init ( LsgFrustum * self,

const Matrix projection,

const Matrix modelview

)

Constructor method for LsgFrustum.
Parameters:

self The instance variable

projection The projection matrix

modelview The modelview matrix

void LsgFrustum_transform ( LsgFrustum * self,

const Matrix projection,

const Matrix modelview

)

Transform a view frustum.
Parameters:

self The instance variable

projection The transformation matrix for the projection matrix

modelview The transformation matrix for the modelview matrix

void LsgFrustum_updatePlanes ( LsgFrustum * self )

Update the clipping planes after transforming the defining projection and/or modelview matrix.
Parameters:

self The instance variable
