Type offers 2 options: Ambient Occlusion and Light Map Destination offers: Texture and Vertex 回答1: For me, it crashes Xcode. It's supposed to render lighting (specifically shadows) into the textures on objects so you don't need static lights. This should, theoretically, mean that all you need in your scene are the lights used to create dynamic lighting on objects that move, and you can save all the calculations required to fill the scene with

I am trying to render text in my OpenGL program using FreeType2 (2.5.3), based on this tutorial: http://en.wikibooks.org/wiki/OpenGL_Programming/Modern_OpenGL_Tutorial_Text_Rendering_02 , using the same structs as Bentebent did in his question (above). I am having the same problem he was having with rectangles showing up instead of legible characters (even using the correct GL_TEXTURE0 parameter for glActiveTexture() ) For example, rendering green strings "Hello" and

In my Java class I have written this line private Texture texture = new Texture(Gdx.files.internal("data/folder_name_1/folder_name_2/abcd.png")); and my robovm.xml looks like this- Info.plist.xml ../android/assets ** true data When I try to run the code on iOS simulator it runs fine. But when I try to run it on an iOS device i.e. iPhone. It generates an error which looks like this- com.badlogic.gdx.utils.GdxRuntimeException: Couldn't load file: data/folder_name_1/folder_name_2/abcd.png

Struggle: finding clear and consistent documentation regarding how to use shadow2D and sampler2DShadow. Here's what I'm currently doing: In the fragment shader of my final rendering pass (the one that actually calculates final frag values), I have the MVP matrices from the pass from the light's point of view, the depth texture

I know that I am able to import the geometry fine, because when I assign a MeshNormalMaterial to it, it shows up great. However, if I use anything that requires UV coordinates, It gives me the error: [.WebGLRenderingContext]GL ERROR :GL_INVALID_OPERATION : glDrawElements: attempt to access out of range vertices in attribute 1 I know this is because the loaded OBJ has no UV coordinates, but I was wondering if there was any way to generate the needed texture

For example I have the blue rectangle texture, and I want to draw red rectangles on top of this blue rect. However i want them to restrict the render only on this rectangle. Like the following image: I read something about texture blit between them or something like that but im not sure if this is posible. My code looks like this: SDL_RenderCopy(ren,bluetexture,NULL,dBLUErect); SDL_RenderCopy(ren,redtexture,NULL
