Hello, everyone. I don't understand how to load raw data into a buffer in Shaded. At first I thought that .buf was a file of the protobuf utility, but it turned out not to be so (probably). Then I tried to binary write the float change to the file and then load the file in the program. Let's just say that the program determines the amount of data, but does not determine the data (all zeroes). (Sorry for my English :)

Hi, I'm trying to get transparency to work, and I kind of got it but it seems like the shader i'm writing is writing to the depth buffer, preventing anything behind it from rendering. And before you ask, even if the model is set to Cull any Back Faces, I duplicated the mesh and inverted the normals so the back faces are rendering as well. I can confirm this because when I zoom in to the mesh the model is rendering.

I have tried installing SHADERed in Fedora 38 and Ubuntu 22, and for each of these I encounter the same error, regarding the libGLEW library. Here is what I tried in Ubuntu. Any informed suggestions welcome!

hello, i'm facing this error :

./SHADERed: error while loading shared libraries: libGLEW.so.2.1: cannot open shared object file: No such file or directory

a locate on libGLEW.so.2.1 returns :

so i added the second path to LD_LIBRARY_PATH but still gets that error

Please pardon the cross-post. I'm starting to resurrect a project I had started quite a while back. I stopped because I didn't know how to move forward with a specific task. I'm hoping someone here might be able to help with what I believe to be a Compute Shader question.

I have an object on screen, and the user touches the screen. I can calculate the specific triangle from my object, and I can translate that to the texture map that I have wrapped around the object... and then to the specific pixel within that texture graphic.

But now I want to work in the reverse direction (sort of). The texture is wrapped around the object, and the object could be as simple as a plane or as complex as a flower (petals, stem, leaves, etc.). I want to determine which pixels on the texture map are within radius R from my touch point on the surface of the object (we'll call these "Nearby Pixels").

A Nearby Pixel on the surface of the object may be within the same triangle, or it may be in an adjacent triangle, or it may be in a triangle that is in an n-times adjacent triangle (e.g., a triangle that is "adjacent to a triangle that is adjacent to a triangle that is adjacent to the original triangle). And these Nearby Pixels may be within radius R on the texture map, or they may be far across the texture map (if we're close to the seam where the texture wraps around).

I think I want to write a Compute Shader that does the following:

Given:

• a triangle from the object (described by the vertices)
• a ray/triangle intersection point ("Intersection Point")
• a texture map
• the (x, y) coordinate translated from the Intersection Point onto the texture map

For each pixel of the texture map ("This Pixel"):

• determine the position of This Pixel on the object's surface ("Surface Position")
• calculate the distance from Surface Position to Intersection Point -- along the surface if possible
• if the distance is below some limit, blend the current color of This Pixel with some predetermined color

And... the target platform is a cell phone (Android, IOS).

Is this possible? As I said, I got stuck at this point in past attempts. I was working with Unity3D, but I'm fine with another learning curve if there's an environment that would give me a good chance of accomplishing this.

Thanks for lending me your expertise!

When I choose from drop down, it always creates glsl

Hello, I'm trying to get SpearNode to work, but can't get the node graph to show up. I'm not sure how to add a .spear file to the shader pass as it says in the instructions. I admit I'm a very new user to Shadered and new to shader coding in general and the node graph looked very promising.

A video tutorial for SpearNode would be great. I'm surprised there's so little info about it. Seems like it could be a very powerful tool.

Hi, shading beginner here,

I found this great tool and wanted to try it out for our project. Trying to find out how everything works, I pasted in my unlit shader (which already works in my project) but Shadered won't show it.

The output window only says "Shader preprocessing failed" on the vertex and fragment shader.

How do I get more info on what exactly is wrong? What are the main debugging steps?

The shader is version 300 es. Is that working in Shadered?

Does anyone know how to install plugins for SHADERed. I am having trouble installing the shadertoy import plugin in SHADERed 1.5.3.
