Detailed Description

The simplest kind of CkView: a single, flat quadrilateral OpenGL texture.

You specify the texture, corners, and draw style.

Member Enumeration Documentation

anonymous enum

These are the XYZ universe locations of the vertices of our texture image.

These go in a fan, like: corners[0]==image.getPixel(0,0) corners[1]==image.getPixel(w-1,0) corners[2]==image.getPixel(w-1,h-1) corners[3]==image.getPixel(0,h-1) Subclasses MUST set these fields on the server.

Enumerator:

maxCorners

Constructor & Destructor Documentation

virtual CkQuadView::~CkQuadView

(

)

[virtual]

CkQuadView::CkQuadView	(	int	w,
		int	h,
		int	n_colors
	)

Create a new quad view to display a new texture.

n_colors should be 1 (greyscale, luminance), 3 (rgb, no alpha) or 4 (premultiplied rgba).

Be sure to set the "corners" and "id" fields after making this call. (SERVER ONLY)

CkQuadView::CkQuadView

(

CkMigrateMessage *

m

)

Migration constructor-- prepare for pup.

(CLIENT ONLY)

virtual void CkQuadView::render	(	double	alpha,
		CkView *	old
	)			[virtual]

Render our image to the current OpenGL context.

Use "alpha" fraction of your own pixels; "1-alpha" fraction of the "old" pixels. "old" may be NULL.

(CLIENT ONLY) So the server can link without OpenGL, all OpenGL calls made by this routine should be protected by an ifdef CMK_LIVEVIZ3D_CLIENT

Implements CkView.
