Possible bug in the source code
Apr 22nd, 2005, 5:41pm  
I've been looking at the source code, haven't had time yet to setup the CVS in order to build and test things.  But I think this line looks a bit unusual:

FILE: processing/core/PGraphics3.java
METHOD: protected final void add_triangle_with_clip(int a, int b, int c)
LINE: ~1187
CONTEXT:
Code:

...
protected final void add_triangle_with_clip(int a, int b, int c) {
    boolean aClipped = false;
    boolean bClipped = false;
    boolean cClipped = false;
    int     clippedCount = 0;

    [b]cameraNear = -8;[/b]
    if (vertices[a][VZ] > cameraNear) {
	aClipped = true;
	clippedCount++;
    }
...

COMMENTS:  It looks to me that each time it adds a triangle with clipping it resets the cameraNear plane to -8.


An extra comment, is that I can't find where the cameraFar plane clips out the triangles, lines,...

yeah, simon's in the midst of getting clipping to happen properly, so things are a little funny in the meantime. he was unfortunately sidelined by another deadline so i think he's gonna pick it up sometime next week. since clipping was completely absent in previous versions, we included the incomplete stuff since it was at least a start and better than nothing.

i think this has been ironed out in the meantime, but if not, please re-post a bit of code that will show the problem over in the bugs db. http://dev.processing.org/bugs
