fragment-shader

I have been trying to use texture2d_array for my application of live filters in metal. But I'm not getting the proper result. Im creating the texture array like this, Code: Class MetalTextureArray . class MetalTextureArray { private(set) var arrayTexture: MTLTexture private var width: Int private var height: Int init(_ width: Int, _ height: Int, _ arrayLength: Int, _ device: MTLDevice) { self.width = width self.height = height let textureDescriptor = MTLTextureDescriptor() textureDescriptor.textureType = .type2DArray textureDescriptor.pixelFormat = .bgra8Unorm textureDescriptor.width = width

I'm working on a program using GLSL shaders. I coded 2 different ways to compute ADS (Ambient + Diffuse + Specular) shading in 2 different methods. To do the job properly I used subroutines to use one or the other method to compute ADS shading. Here's a piece of the fragment shader code : subroutine vec3 LightShadingEffectType(int idx, vec3 normal, vec3 lightDir); subroutine uniform LightShadingEffectType LightShadingEffect; subroutine (LightShadingEffectType) vec3 Basic_ADS_Shading(int idx, vec3 normal, vec3 lightDir) { vec3 reflectDir = reflect(-lightDir, normal); vec3 viewDir = normalize(

I am creating a videogame in Unity. Every sprite is rendered with a Sprite Renderer with a Material that has the CornucopiaShader.shader. The problem I have is I want to limit the max brightness (or color) of the sprite to just be a normal image of the sprite regardless of the power of how many point lights are hitting it, the intensity of the lights, and also the ambient light in the unity scene. When the intensity of the lights hitting the sprite is below that max brightness level I want it to act like a normal lit sprite and be black if no lights are hitting it, and be half lit up if an

I'm playing around and trying to implement Metal shader in SceneKit that will outline an object. The idea is to draw an outline (or silhouette) similar to this image found in this blogpost (the blogpost doesn't contain any code): I'm new to SceneKit and Metal shaders so I'm able just to draw some geometry and write simple vertex or fragment shader. I'm curious how can I achieve this kind of effect? Is it done in multiple passes? Cheers! The basic idea here is to clone the "selected" node and its geometry, then use a custom vertex and fragment shader to "push" the geometry out along the vertex

Can anyone provide me the shader that are similar to the Fixed function Pipeline? I need the Fragment shader default the most, because I found a similar vertex shader online. But if you have a pair that should be fine! I want to use fixed pipeline, but have the flexability of shaders, so I need similar shaders so I'll be able to mimic the functionality of the fixed pipeline. Thank you very much! I'm new here so if you need more information tell me:D This is what I would like to replicate: (texture unit 0) functionality of glTranslatef functionality of glColor4f functionality of glTexCoord2f
