• Michael Luttmer Distorted texture after lost/reset device

  Hi, I'm drawing a textured mesh using DrawIndexedPrimitive, using an effect interface. After a windowed/full screen toggle the texture appears distorted. Interestingly when I draw another mesh in wireframe mode in the same render call the problem doesn't occur. Can somebody help Nico I just dumped the tex coords before rendering the mesh with the undistorted texture and than before rendering the distorted v ...Show All

• Jeremy Balliston Setting a color mulitplier for a device

  I have a number of objects which are aranged in a tree structure in a child parent relationship. When a parent renders, it sets the transformations, that it uses and then renders its children, which in turn sets their transformations by multiplying on the current world transform. That is pretty basic and pretty standard. Now I would like for children to "inherit" and modify the parents color as well. If a parent has the RGBA c ...Show All

• Oliver Berris [GDI+] ColorMatrixEffect

  I am not sure where a GDI+ question is supposed to be posted, so feel free to move it if it should be somewhere else.

• Mydotnet Single or Double for vector floats?

  as i'm new to this. i was wondering if your only allowed single floats for vectors etc in directx. most of the code i've seen only has single float values. as i wanted to use the following unit scale 1.000 = 1 meter, 0.100 = 10cm, 0.001 = 1mm. with a max value of 99999.999 i think i'll need double floats for using this. so would i get away with this ahh thanks for that info. i was doing some testing in visual ...Show All

• Brian Sullivan How to Mirror/Reflect/Flip a texture vertially?

  Hi, I've previously developed a small .Net 1.1 application that converts from TGA and DDS files to the native texture files of a game (Dawn of War). The problem is that not everyone wants to then get additional plugins (or can't get plugins) to read the DDS files or convert them to TGAs for editing. Instead, I'm trying to use the DirectX SDK to convert between TGA and DDS (DXT1) without the need for an additional app. The general conversi ...Show All
