RwIm2DCameraVertex

Detailed Description

Requirements

Headers: rwcore.h
Libraries: rwcore.lib

These two macros are used to set the RwCameraVertex texture coordinates together with those of an RwIm2DVertex.

As both vertex types are frequently worked on together, using these macros can save some typing. They are defined as follows:

Warning:

Do not use these macros on platforms with hardware-accelerated transform and lighting stages.

#define RwIm2DCameraVertexSetU(devvert, camvert, camu, recipz)  \
    MACRO_START                                                 \

void RwIm2DCameraVertexSetU	(	RwIm2DVertex *	devvert,
		RwCameraVertex *	camvert,
		RwReal	u,

	)

RwIm2DCameraVertexSetU is used to define the texture u-coordinate of the specified device and corresponding camera vertices.

Parameters:

devvert	A pointer to the device vertex
camvert	A pointer to the camera vertex
u	An RwReal value equal to the texture u-coordinate
reciprocalZ	An RwReal value equal to the reciprocal z-coordinate (for perspective correction purposes).

Returns:: None.
