Replace the above with :



glConvolutionFilter2D(
GL_CONVOLUTION_2D,
GL_LUMINANCE16,

Yup, that's it ... thanks :)

Can you be a little more specific on what you mean by 'reloading'? Are you talking about sequences of images that display in a loop then repeat?

I've written a viewing tool that displays static frames and sequences of FLIR imagery. The image pixel data is loaded per frame and stored in unsigned short array. The dynamic range of the luminance...

Is this possible? I don't mean the maximum texture size the video card can handle, I mean the total amount of texture RAM on the board.

Thanks, I ordered that book from amazon.com last night.

I turn up all sorts of tutorials when I google for help and I found that site too. Did you learn by perusing that site?

I can google...

I'm lagging way behind the technology curve and so far I haven't done anything at all with shaders. In fact, I really don't understand much about them at all. I now have a couple of free days here at...

You must be doing something else wrong then ...
Maybe post some code?

Many games provide an option to use either OpenGL or DirectX. I use OpenGL whenever possible just out of principle ...

No Ideas?

I would start with a Delaunay Triangulation algorithm such as that here (http://codeguru.earthweb.com/Cpp/data/mfc_database/misc/article.php/c8901/) then add data structures and code to disallow...

I want to roll stabilize my quaternion based scene navigation camera class. In order to do this I need a quaternion operation that will set the rotation about one axis to zero while preserving the...

I would benchmark the two as previously recommended but my instincts tell me that float would be faster. Think about it ... sending a million float vertices over the pipeline versus sending a million...

Do a google search on the following ... you will find lots of formulas for computing similar stuff. Your application in particular is SSS

How did you manage to map the textures onto the sphere?

Yes, I was speaking of the maximum texture dimension (size). Is that for all models of the Fx?

We have some ultra high resolution imagery (4096 pixels+) that we wish to map onto a sphere for an earth model in one of our analytical tools. The better cards we have here at the shop report a...

Actually it doesn't fit in any of the forums here as it doesn't relate to OpenGL at all.

Read UrbanLegend's response ... C++ is your friend.

FYI ... Thought I would share ...

Here is a slick way to get the window handle in GLUT without getting the GLUT source code and modifying it.

Actually billboarding can be used to show such motion; I do it frequently using a C++ class I wrote called a FilmStripQuad. Just load several textures (such as leaves in position #1, position #2,...
