RenderMan & RISpec >> Dump Grid

by Bo Schwarzstein » Sun, 27 Apr 2008 14:11:27 GMT

Hi everyone !
I am working on how to dump the shading grid. I follow the dumpgrids.c
from Matt Pharr, but I found that when I try to output some polygon
models from maya, Prman will show a memory error, I check the output
data, lot's of 0.000000, even NaN floating number, there must be some
wrongs in this progress. But if I convert the models to subdivide
surface, that everything is good, no lot's of 0.000000, no NaN, but if
I do like this, I will not get the original models, so How should I
dump grid from prman correctly ?

2. Minor angular grid lines in polar grid? 

Dear all,

I am looking for possibility to draw minor tic gridlines in polar grid 
mode. According to the description in gnuplot.pdf there seems to be only 
one grid line level for the angles. However, I would like to set also 
minor grid lines, e.g. the major ones in 30 degree steps and the minor 
ones in 10 deg steps.

Is there any possibility to do so without hacking my own lines via 
arrows or so?

4. dump of D3DCAPS9 

Hello,

Is anyone aware of a utility which can print the contents of the D3DCAPS9 
structure to a file with all of the capabilities listed as strings exactly as 
would be listed by DXCapsViewer? We would like our users to be able to 
generate such a file so that they could email it to us for diagnostic 
purposes.

6. Dumping DirectX frames to movie file 

What do people use in C++ to dump DirectX 9.0b frames to disk?

I know about the avifil32.dll approach to create AVI streams from buffers
and I know about the DirectShow method (like DirectX.Capture).

I am looking for a C++ solution that works for people from within their own
application (i.e. not an external utility).

Any thoughts on what works and what doesn't?

Basically I want to capture some DirectX flythroughs from within my
application so the user can view these later with Media Player.

Thanks,

dave

8. GDI+ Graphics Dump 

Hi all -

I'm a complete noob when it comes to using the system.drawing
namespace.

I'd like to draw a control to an image instead of on screen (the object
shouldn't appear on screen at all). Any ideas?

I was trying to use control.createGraphics, but it doesn't appear to
have any options to save the data to a different surface...

Is there any way to use the graphics object to draw to multiple
surfaces simultaneously?

Thanks,

-Mark
