would be very useful to be able to at the very least view the code, I do most of my shader development using Shaderific, Codea, and Verto Studio on iOS and its impossible to copy or edit code from the ShaderToy site on iOS.

I compile this app in Xcode, but many shader show info just like "ERROR: 0.40: Use of undeclared identifier 'iTime'". So I changed 'iGlobalTime' into 'iTime', but this shader "Creation by Silexars" can't work successfully in my phone. Anbody know why?

Hi there,

I've just installed the app from the app store on my iphone and it is unable to create a GL context in the shader viewcontroller, leading to a "shader error" message. From a quick glance at the app code I'm guessing it may have something to do with the GL ES version. I'll dig around and try to find a fix.

I'd be willing to help develop one, though I probably wouldn't have time to do it solo.

My iPhone 5 doesn't support WebGL 2.0, i would therefore be glad to see a compatibility mode to support WebGL 1.0 shaders, like the website does. At the moment i just get the error message "Failed to create ES context".

This was the only link from the API docs, so I'm opening this issue here.

The most basic API usage, like https://www.shadertoy.com/api/v1/shaders/4s2SRt?key=rt8tWH doesn't seem to work, as it gives error:

{
  "Error": "Shader not found"
}

Even though I've just copied the code from URL of a working shader.

Context: trying to use glslViewer/glslLoader to study ShaderToy shaders, but the importer cannot work because of the API errors: patriciogonzalezvivo/glslViewer#93

Why application does not see Chimera's Breath shader? Here is API response:

{
    Error = "Shader not found";
}

Maybe some shaders are hidden.

From my reading of this code:

• when a target has filter type 'mipmap' on it, it looks like every time that target is bound as a source in a pass, glGenerateMipmaps is called; even if the target has not been updated. For example, if Pass_A writes to target A, then Pass_B, C, D will each regenerate the mipmaps, even if the target has not been touched again.
• every time an audio input is supplied to a shader, it looks like a new upload of the sound buffer data is done, even if a new frame of audio has not been delivered. It's clear that the FFT is done once per frame of audio, but I believe the texture upload is happening every time.

Hi,

Did a "pod install" on main dir, but still numerous errors when trying to build in Xcode 12.x.

Recommendations?
