[Solved] Refraction with Framework

[L B]

Trying to use refraction with framework, I found myself stuck having to get the rendering buffers, which I can't access. Example:

 

(Reference tutorial: http://www.leadwerks.com/files/Tutorials/CPP/Transparency_And_Refraction.pdf)

 

using System;
using Leadwerks;
using Math = Leadwerks.Math;

namespace Evol
{
   static class Refraction
   {
       static void Main()
       {
           try
           {
               Engine.Initialize(800, 600);
               Framework.Initialize();
               FileSystem.Initialize(@"C:\Users\Lazlo\Desktop\Refraction");
               Filtering.Optimize();

               Explorer ex = new Explorer(Framework.Camera);
               ex.Camera.Position = new Vector3(0, 2, -2);                

               Mesh scene = Mesh.Load("abstract::scene.gmf");

               World.Current = Framework.Layers.Transparency.World;

               Mesh sphere = new Mesh.Sphere();
               sphere.Material = Material.Load("abstract::glass_refraction.mat");
               //sphere.Material.Textures[2] = Can't get the framework's light buffer?
               //sphere.Material.Textures[3] = Can't get the framework's graphic buffer?
               sphere.Position.Y = 2;

               World.Current = Framework.Layers.Main.World;

               float refractionStrength = 0.01f;

               while (!Window.HasRequestedClose)
               {
                   ex.Update();

                   if (Keyboard.KeyDown(Key.Up))
                   {
                       refractionStrength += 0.001f;
                   }

                   if (Keyboard.KeyDown(Key.Down))
                   {
                       refractionStrength -= 0.001f;
                   }

                   refractionStrength = Math.Max(refractionStrength, 0);
                   sphere.Material.Shader.Pass("refractionstrength", refractionStrength);

                   Timing.Update();
                   Framework.Update();
                   Framework.Render();
                   Graphics.Flip();
               }
           }
           catch (LeadwerksException e)
           {
               Debug.Alert(e);
           }

           try
           {
               Framework.Dispose();
               Engine.Dispose();
           }
           catch { }
       }
   }
}

Trying to use refraction with framework, I found myself stuck having to get the rendering buffers, which I can't access.

I had the same problem, but because I'm using framewerk and not framework I was able to amend the framewerk adding my own additional functions for suporting refraction.

 

Guess you need to request Josh do likewise in the embedded framework!

[L B]

Requested Josh, he said it is not possible at the moment, but that he would try to implement GetFrameworkGraphicsBuffer and GetFrameworkLightingBuffer eventually, which could be in some time.

 

What are your suggested alternatives? Building my own Framewerk, or what?

I actually solved it with this material file:

texture0="abstract::glass.dds"
texture1="abstract::glassdot3.dds"
texture2="tag::rendercolor"
texture3="tag::renderdepth"

depthmask=0
zsort=1
shader="abstract::mesh_diffuse_bumpmap.vert","abstract::mesh_diffuse_bumpmap_refraction.frag"

Thanks to Lumooja for the firepit reference suggestion.

Yeah, never judge someone who is marked by experience. He may not be benevolent to your current fashion, but in the end he will show you the right way.

[Pixel Perfect]

So you can reference the color and depth buffers in a material file ... interesting

[macklebee]

yes... as shown in Josh's refraction example that he had provided in the tutorial for transparency and refraction... At the bottom of the tutorial, he even added a scripted model to use inside the Editor. Tutorials are our friends!
