Coordinate systems on on nv10-era cards
Hello,
I'm trying to debug why fbo-copyteximage-simple is failing, and I'm...
failing. It's an extremely simple test. I'm pretty sure that the
copyteximage part of it has nothing to do with the failure, at least
it behaves identically when I just return tex instead of copiex_tex.
Without any modifications, the test just renders one big red square. I
think there's something

Coordinate systems on on nv10-era cards
So I did a lot more debugging on this. I wrote a program that draws a
triangle to an fbo, and then blits that to fb 0. If I draw the
triangle with
glBegin(GL_TRIANGLES);
glColor3f(1, 0, 0); glVertex3f(-0.6*128 + 128, -0.75*128 + 128, 0.5);
glColor3f(0, 1, 0); glVertex3f(0.6*128 + 128, -0.75*128 + 128, 0);
glColor3f(0, 0, 1); glVertex3f(128, 0.75*128 + 128, 0);
glEnd();
Then all is well. However if I do:
float verts[3][6] = {
{ -0.6*128 + 128, -0.75*128 + 128, 0.5, 1, 0, 0 },...

more one question regarding gl and nouveau
Hi, for example, if I have glVertex3f(0.75, 0.75, 1.0) how the video card
processes
these three floats? Does the card work with floats? Does (mesa? gallium?
driver?)
process these three input floats before it is sent to the card? Where is
the code
for it?
If you say the floats are memory mapped as in
exec->vtx.buffer_map = (GLfloat...

Graphical text error in game (MI5)
Hi, have recently bought MI5 (Tales of Monkey Island), and I am currently trying to run it under wine in Ubuntu 9.04 and I am running the latest development version 1.1.25. I am running this over the latest stable version due to less graphical errors when trying to run the game.
To get the game running I followed this guide posted on the telltale's ( the creators of the game) forum

a few questions about OpenGL and nouveau
...t; is done through st_draw_vbo() which would end
up
calling nv30_draw_vbo() which would send data to the card... but where is
the
missing link?? The floats (for the vertices and color) are already mapped by
ctx->Driver.MapBufferRange...*/
glBegin(GL_LINES);
glColor3f(1.0, 1.0, 1.0);
glVertex3f(0.0f, 0.0f, 0.0f);
glVertex3f(50.0f, 50.0f, 1.0f);
glEnd();
}
glXSwapBuffers();
}
Thanks in advance.
