I have a lot of images taken from a 360 camera which I would like to be able to display in Silverlight 3. They are NOT regular panorama images. The camera which took the image actually creates a distorted jpeg that becomes undistorted once wrapped around a sphere as a texture. I have desktop software that will allow viewing of the image ...
I have a black and white 2D drawing of a silhouette (say, a chess piece) that I would like to rotate around an axis to create a 3D object. Then I want to render that 3D object from multiple angles using some sort of raytracing software, saving each angle into a separate file. What would be the easiest way to automatically (repeatedly) ...

I need to create a Direct3D mesh consisting of some vertices (generated at run-time) which I need rendered as a combination of LineList and TriangleList. i.e. some vertices are rendered as a LineList and some of them as a TriangleList. How can I create this Direct3D mesh? ...
I've been fussing with this for the better part of the night, so maybe one of you can give me a hand. I have found GDI+ DrawImage in C# to be far too slow for what I'm trying to render, and from the looks of forums, it's the same for other people as well. I decided I would try using AlphaBlend or BitBlt from the Win32 API to get better...
I'm trying to replace a color for something that is drawn on a Canvas using AvoidXferMode. From the android docs it looks like it's exactly what I need: AvoidXfermode xfermode will draw the src everywhere except on top of the opColor or, depending on the Mode, draw only on top of the opColor. What I'm trying is something like this:...
I've got a list of objects (probably not more than 100), where each object has a distance to all the other objects. This distance is merely the added absolute difference between all the fields these objects share. There might be few (one) or many (dozens) of fields, thus the dimensionality of the distance is not important. I'd like to d...

Histograms and scatterplots are great methods of visualizing data and the relationship between variables, but recently I have been wondering about what visualization techniques I am missing. What do you think is the most underused type of plot? Answers should: Not be very commonly used in practice. Be understandable without a great de...
I've been trying to find info on performance of using float vs double on graphics hardware. I've found plenty of info on float vs double on CPUs, but such info is more scarce for GPUs. I code with OpenGL, so if there's any info specific to that API that you feel should be known, let's have at it. I understand that if the program is mov...

I'm writing a 2D animation class, and I've got TGA pictures in which the player animation is stored. These pictures are 8x8 tiles (so on each row there are 8 frames of a moving character) However, I don't have a clue on how to animate this in code. I was thinking about updating it by moving the u-v coordinates each frame and returning ...

That is, I want to display only that graphic and not the form back ground or title bar or anything. I want to display only that graphic. But the thing is I'm not able to sha...
I'm doing a bit of retro programming for fun. What I want to create is a DOS game using EGA graphics but I am having a bit of trouble finding a good reference on the web. Everybody who talks about doing DOS programming assumes that the programmer will use mode 13h, and although some pages mention the other graphics modes, I haven't fou...
