I have a complex SCNGeometry representing a hexasphere. It's rendering really well, and with a full 60fps on all of my test devices. At the moment, all of the hexagons are being rendered with a single material, because, as I understand it, every SCNMaterial I add to my geometry adds another draw call, which I can't afford. Ultimately, I want to be able to color each of the almost 10

I have a lot of PNG's right now and I need to reduce the amount of memory they take up. I was looking at PVR compression but I can't figure out how to use this within OpenGL. Could some point me in the right direction or offer some examples as I cannot find anything. 回答1: There are mainly four texture compression types supported on Android: ETC1 (Ericsson texture compression) . This format is supported by all Android phones. But, it

The texture is defined as follows: texture<float, 2, cudaReadModeElementType> cornerTexture; The binding and parameter settings are: cornerTexture.addressMode[0] = cudaAddressModeClamp; cornerTexture.addressMode[1] = cudaAddressModeClamp; cornerTexture.filterMode = cudaFilterModePoint; cornerTexture.normalized = false; cudaChannelFormatDesc cornerDescription = cudaCreateChannelDesc<float>(); cudaBindTexture2D(0, &cornerTexture, cornerImage->imageData_device, &cornerDescription, cornerImage-

I googled the crash but got no results. Also this only happens when I go back to my first scene after coming back from the second scene in my game. I double checked my code and I make sure all the images in my sprite sheets are added as children to the batch node. I also make sure the images in my app that aren

I am using opengl 4. If I try to do this using a 4 channel RGBA texture it works perfectly fine but for whatever reason when I try and load in a single channel only I get a garbled image and I can't figure out why. I create the texture by combing texture bitmap data for a series of glyphs with the following code into a single texture: int texture_height = max_height * new_font->num_glyphs; int texture

However, I can't find any good examples of saving this as a file to local storage as a jpg, for example. The ARCore examples have a nice example of retrieving the camera data and then doing something with it here: https://github.com/google-ar/arcore-unity-sdk/blob/master/Assets/GoogleARCore/Examples/ComputerVision/Scripts/ComputerVisionController.cs#L212 and there are a few examples of retrieving the camera data in that class, but

To achieve that I try to use key-value coding setting parameter of type SCNMaterialProperty . From SceneKit manual on SCNMaterialProperty property contents : You can set a value for this property using any of the following types: ... A texture (SKTexture, MDLTexture, MTLTexture , or GLKTextureInfo) ... So, I construct MTLTexture : Create MTLTextureDescriptor with type MTLTextureType2DArray Create

Unfortunately, the result is that the texture is projected entirely on each face, instead of using only the corresponding part: let videoGeometry = SCNBox(width: 1, height: 1, length: 1, chamferRadius: 0) videoGeometry.firstMaterial?.isDoubleSided = true videoGeometry.firstMaterial?.diffuse.contents = UIImage(named: "test")! I know I can use shader modifiers on the geometry but I'm not sure where to get

Usually a Framebuffer is used so the result of the computation is stored in a texture. Also the input data is usually a texture. To improve performance it would be great to get rid of glTexImage2D and glReadPixels to upload and download images to and from the GPU memory space. All the code related to OpenGL is native. On Android GraphicBuffer can be used on Android for this propose because in mobile devices gpu memory is just host RAM memory. This structure allows

My Android device support OES_texture_float . but, it became an error to attach GL_FLOAT texture. In OpenGL ES 2.0 in Android, to attach GL_FLOAT texture to FBO is impossible? Or depend on hardware? Part of my code is: Init: glGenTextures(1, &texture); glBindTexture(GL_TEXTURE_2D,texture); glTexImage2D(GL_TEXTURE_2D,0,GL_RGB,texWidth,texHeight,0,GL_RGB,GL_FLOAT,NULL); FBO Attach: glBindFramebuffer(GL_FRAMEBUFFER,framebuffer); glFramebufferTexture2D(GL_FRAMEBUFFER,GL_COLOR
