1.0f for second one. Running this will result in segfault. The segfault is caused byBuildTextureArray()function (it would run without it, but there would be no array texture of course). I have tried to create that function according toHow to use GL_TEXTURE_2D_ARRAY in OpenGL 3.2, so ...
In 4.5+ OpenGL, one can access a textures' data by giving a texture ID by using the glGetTextureImage() function. For example in order to get a GL_RGB texture data, we have 3 floats R,G,B each one of each is 4 bytes so: float* data = new float[texture_height * texture_width...
rename tex01 to webcamtex to avoid confusionand don't forget (like me in first place) to addquad = gh_mesh.create_quad(winW, winH)shadertoy_prog = gh_node.getid("shadertoy_prog")update_scene:gh_texture.bind(webcamtex, 0)gh_utils.webcam_grab_frame(webcam1)gh_utils.webcam_update_...
OpenGL provides a lot of flexibility in how it reads data from textures and returns it to your shader. Usually,texture coordinatesare normalized—that is, they rangebetween0.0 and 1.0. OpenGL lets you control what happens when the texture coordinates you supply fall outside this range. This is...
The context is a 2D sprite: a simple texture painted on a quad. All done with OpenGL ES 2.0. My very basic goal is a simple blur filter using a 3x3 Kernel with average weights: every pixel used is weighed 1/9th and summed up. Besides many ways to improve the performance...
Find the templatebuiltin-spriteand copy it to the effect you just created. Create a new materialhoverSprite, select it, in effect, tick theTEXTUREwe just built. TickUSE TEXTURE. Drag the hoverSprite material into the Sprite Node’s CustomMaterial of cc.Sprite. ...
Some of the “main” settings, such as texture quality and anti-aliasing, are the most demanding. Unfortunately, they also matter the most when it comes to visual quality. Turn down texture quality if you have limited video memory and try to use lightweight anti-aliasing like FXAA instead ...
The idea is to create a cube map with procedurally generated noise, extract the noise and a normal map of the noise for all six sides via a render target and a orthographic camera, download it as an image, and then read it back as a texture. The problem is when reading back the norm...
It is also worth mentioning that the Android SDK and NDK together allow you to write OpenGL ES-related code in both Java and C. 2.Project Setup Because the OpenGL ES APIs are a part of the Android framework, you don't have to add any dependencies to your project to be able to use ...
Add a Comment Replies You would need to use CVMetalTextureCacheCreate and CVMetalTextureCacheCreateTextureFromImage. There are some examples of this API in the "Mixing Metal and OpenGL Rendering in a View" sample, albeit for a different use case. Posted 3 years ago by Graphics and Games Eng...
