Allright... problem solved. I simply forgot to release all references to the device :) Thanks anyway! http://www.aschratt.com

Thanks. I found something like that too, haven't got that working yet. ¡El diablo está en mis pantalones! ¡Mire, mire! SELECT * FROM User WHERE Clue > 0 0 rows returned Save an Orange - Use the VCF! Personal 3D projects Just Say No to Web 2 Point Blow

I gave you two suggestions, did you try either of them? MVP 2010 - are they mad?

Thanks, I'll try that out. ¡El diablo está en mis pantalones! ¡Mire, mire! SELECT * FROM User WHERE Clue > 0 0 rows returned Save an Orange - Use the VCF! Personal 3D projects Just Say No to Web 2 Point Blow

Also this article has some insights on the W7 and GDI/GDI+/2D rendering.

Luc, Thanks for the link. A colleague of mine has actually been writing the code, I haven't seen too much of it. I know he's tried captureing the DirectX frames as BMps, then using Windows Media Encoder to merge them into a WMV, but the frame rate has never been quite right. He might not have seen the IWMEncVideoSource2 type, which looks like exactly what we need. Hopefully the performance will be decent on it.

One thing at a time. Let's look at the vectors first. Each vector arrow will consist of two elements - a line and an arrowhead. The length of the line should be related to the magnitude of the vector, and it should be rotated to match the angle implied by the two cartesian components (U and V). The lines should probably be scaled so that the longest one stretches completely across it's 'cell' in the vector field, without reaching into adjoining cells. The arrowhead is a little trickier. You need to work out the dimensions for the basic triangular shape you'll want, with it pointing, for instance, stright up. The shape will be defined by the locations of the three corners, relative to the center of the arrowhead. Then modify your arrowhead code so it'll take an angle as a parameter, and will render the arrowhead rotated to that angle. (Hint- if you define the arrowhead by it's corners, you should be able to apply the rotation to the corners and then draw the triangle. That should get you started, anyway. :)

thanks tim. You are correct about the problem. But I dont have background color as a seprator because of cloud color. Without this clude I am using the fore and back color distance logic to get the correct color. But with this 3rd color problem is :doh: . Up to no efficient solution for this in case anyone can help with more ideas.

Disable back-face culling - glDisable(GL_CULL_FACE); specify double -sided material properties - e.g., glMaterialfv(GL_FRONT_AND_BACK...); enable double-sided lighting - glLightModelf(GL_LIGHT_MODEL_TWO_SIDE, TRUE).

Once you've created your VBO, you still render it with glDrawArrays (or an equivalent sequence). What may complicate the issue is the fact that you'll have to break up the rendering of the object into a number of steps. Each sub-block that you want to uniquely identify in the hit test will need it's own 'name', and that name will have to be passed to glLoadName before the relevant piece of geometry is rendered. But AFAIK it should work with data stored in a VBO.

There is no stock implementation, but there's a freeware library called Vincent[^] that might meet your needs.

Sorry, I don't know the answer to your query, just hope someone else with the relevant knowledge sees the post.

Hi. If I understand you correctly. the term you're searching for is 'Code Folding[^]'
