• DavidDante Tree shadow

  Hi, I need to draw tree shadow on any object (my terrain has hilliness, and there are also other objects). My trees are made by rectangles with textures (cross-trees).

• J.M. Dussault Using Sprite to draw 2D graphics

  Hi all, I use Sprite class to draw Bitmaps on the screen. In the sprite class, I only know how to do some simple effects on the texture, such as setting the transparency. The problem is that I want those textures to be affected by Lighting. E.g. If the color in the texture is blue, the outcome result is Green. Also I want to do other effects like a spot light on the texture. I have read a book (C++) and seems that I have to use ...Show All

• arv MDXInfo Tutorials

  Hi, I posted this same list on a couple other forums without any replies. Eventually I ended up submitting my own first example and of course it gets marked as resolved. Plegh! Like a number of other beginner's to game programming, I am having a difficult time deconstructing the Microsoft examples. They always throw in the whole kitchen sink! I would like to see some very rudimentary code samples which each do one simple thing. The Di ...Show All

I get no error. The application just freezes on the call to getBackBuffer. I attempt to lock buffer 1 while rendering into buffer 0. How is the graphics device working in relation to threads Can you work on a buffer while renderi ...Show All

• BrentRogers Stencil function

  I have had a hard time finding any usableinfo on the stencil functions, masks etc. Aparently it is regarded as good documentation to describe ReferenceStencil only as "Integer that specifies the stencil test value to set or retrieve" which is no help.   I have a simple scene with two transformed colored quads. A red in front of, and partly covering, a yelow one. I turn off zbuffer write and color buffer write and then render the red o ...Show All
