May I suggest my solution ? (tested on Chrome v92+, Firefox v90+, Edge v92+). A bit of box shadow : #parchment { position: absolute; display: flex; width: 75%; min-height: calc((1vw + 1vh) * 75); /* center page with absolute position */ top: 0%; left: 50%; transform: translate(-50%, 0); margin: 2em 0; padding: 4em; box-shadow: 2px … Read more
SDL_Texture objects are stored as close as possible to video card memory and therefore can easily be accelerated by your GPU. Resizing, alpha blending, anti-aliasing and almost any compute-heavy operation can harshly be affected by this performance boost. If your program needs to run a per-pixel logic on your textures, you are encouraged to convert … Read more
Use ShaderMaterial and set both textures as uniforms, and then blend them within shader. I made this example: http://abstract-algorithm.com/three_sh/ and that really should be enough. So, you make ShaderMaterial: var vertShader = document.getElementById(‘vertex_shh’).innerHTML; var fragShader = document.getElementById(‘fragment_shh’).innerHTML; var attributes = {}; // custom attributes var uniforms = { // custom uniforms (your textures) tOne: { … Read more
You are still using the old syntax for uniforms var uniforms = { texture1: { type: “t”, value: 0, texture: THREE.ImageUtils.loadTexture(“texture.jpg”) } }; This is the new syntax var uniforms = { texture1: { type: “t”, value: THREE.ImageUtils.loadTexture( “texture.jpg” ) } };
From the example images you provided I’m pretty sure you’re looking for UIImage‘s resizableImageWithCapInsets: UIImage *originalImage = [UIImage imageNamed:@”myImage.png”]; UIEdgeInsets insets = UIEdgeInsetsMake(top, left, bottom, right); UIImage *stretchableImage = [originalImage resizableImageWithCapInsets:insets]; [myButton setBackgroundImage:stretchableImage forState:UIControlStateNormal]; // the image will be stretched to fill the button, if you resize it. The values in the UIEdgeInsets struct determine … Read more
How can data not be 1-byte aligned? This strongly suggests a lack of understanding of what the row alignment in pixel transfer operations means. Image data that you pass to OpenGL is expected to be grouped into rows. Each row contains width number of pixels, with each pixel being the size as defined by the … Read more
Is the texture initialized when you call glTexSubImage2D? You need to call glTexImage2D (not Sub) one time to initialize the texture object. Use NULL for the data pointer, OpenGL will then initialize a texture without copying data. answered EDIT You’re not supplying mipmaping levels. So did you disable mipmaping? glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILER, linear_interpolation ? GL_LINEAR : … Read more
I suspect there is some issue with OpenCL in latest NVidia drivers on some video cards. Here and here are some reports about those. Try to repeat test on GPU from another family.
“If it ain’t broke, don’t fix it.” See if you can find anyone telling you why Simplex is better. “It’s faster and extends to multiple dimensions” and “simplex noise attempts to reduce the complexity of higher dimensional noise functions” were what I found. Most of us work in 2 or 3 dimensions, maybe 4 if … Read more
There are mainly four texture compression types supported on Android: ETC1 (Ericsson texture compression). This format is supported by all Android phones. But, it doesn’t support an alpha channel, so can only be used for opaque textures. PVRTC (PowerVR texture compression). Supported by devices with PowerVR GPUs (Nexus S, Kindle fire, etc.). ATITC (ATI texture … Read more
