GL ignores first Vertex ??? (ASM)

Recommended Posts

hi, again I got the problem, that OpenGL doesn''t draw (use) the first vertex: This is MASM code invoke glBegin,GL_LINE_LOOP ;put anything else here _glVertex3f 1.0f,0.0f,0.0f _glVertex3f 2.0f,0.0f,0.0f _glVertex3f 2.0f,1.0f,0.0f _glVertex3f 1.0f,0.0f,0.0f invoke glEnd Nothing wrong I think. Well, @ my pc GL does draw the lines from Vert1->2 2->3 3->4 but not 4->1 It''s a lineloop. Let''s try a quad instead. The 1st Vertex is at the right place every 2nd frame. @ the other frames it''s far, far away left upper out of the screen. I''ve no idea what the problem is. Here''s a link to a Zipfile with Source,Exe,myHeaders and a screenshot. Hope You can help me guys. It''s very important.

Ok guys, I''ve fixed it. But I don''t know if this is the real bug in my code or my CPU

It''s the Floating Point Instructions.

I''ve rewritten them and now it works. Bit tricky now , since I never used the before
Well I''ve never learned Win32 asm

I''ve written a little Effect with it.
Please tell me if it''s running ok on your machine.
(It may be too fast because of no timing
Which one do you like more
cube or cubix both 4k = 6kb zip

Here''s the intro *******

i prefer the cubix. both are working like they should ( i think, i don''t have a reference image or movie to see it, but they look okay )
