project2dTo3d()

bool PureProjection::project2dTo3d ( TPureUInt nScreenX, TPureUInt nScreenY, TPureFloat nScreenDepth, TPureFloat fCamPosX, TPureFloat fCamPosY, TPureFloat fCamPosZ, TPureFloat fCamTargetX, TPureFloat fCamTargetY, TPureFloat fCamTargetZ, TPureFloat fCamUpX, TPureFloat fCamUpY, TPureFloat fCamUpZ, TPureFloat fCamFovY, TPureFloat fCamAspect, TPureFloat fNearPlane, TPureFloat fFarPlane, TPureInt nViewportX, TPureInt nViewportY, TPureUInt nViewportW, TPureUInt nViewportH, PureVector & vecUnprojected )

static

Makes a projection from window/screen-space to world-space.

Makes an unprojection from window/screen-space to world-space.

Parameters

nScreenX,nScreenY	nScreenDepth The window/screen-space position coordinates to be unprojected to world-space.
vecUnprojected	The unprojected 3D world-space coordinates. Valid only if the function returned true.

Returns

True if unprojection is successful, false otherwise.

project3dTo2d()

bool PureProjection::project3dTo2d ( TPureFloat fWorldX, TPureFloat fWorldY, TPureFloat fWorldZ, TPureFloat fCamPosX, TPureFloat fCamPosY, TPureFloat fCamPosZ, TPureFloat fCamTargetX, TPureFloat fCamTargetY, TPureFloat fCamTargetZ, TPureFloat fCamUpX, TPureFloat fCamUpY, TPureFloat fCamUpZ, TPureFloat fCamFovY, TPureFloat fCamAspect, TPureFloat fNearPlane, TPureFloat fFarPlane, TPureInt nViewportX, TPureInt nViewportY, TPureUInt nViewportW, TPureUInt nViewportH, PureVector & vecProjected )

static

Makes a projection from world-space to window/screen-space.

Note that for the projected coordinates, vecProjected = (0,0,z) represents the lower left corner of the window/screen, so if you want to have this projected coordinate vecProjected to be in the same coordinate system as the sticked objects, you need to subtract the half of the camera viewport's width from vecProjected.getX() and the half of the camera viewport's height from vecProjected.getY() because sticked objects have (0,0) as the center of the window/screen as the origin.

Parameters

fWorldX,fWorldY,fWorldZ	The world-space position coordinates to be projected to window/screen-space.
vecProjected	The projected 2D window/screen space coordinates. Valid only if the function returned true.

Returns

True if projection is successful, false otherwise.
