Daz NSRT - first Raytracer (17.08.2019)

[NSware]

Thank you, for your wanted help recreation & Saki_Sliz .
Now i Fix some problems, and work on the Opacity/Transparent Map and Reflections...

I need help for Color-Calculation
If i hit a Triangle with lower Transpanrent and than a Trinagle with non Transpanrent...how i should calculate???

Thank you
Opacity/Transparent test : Specular + Ambient Occlusion + Shadow + Bump Map + Opacity


Specular + Ambient Occlusion + Shadow + Bump Map


Ambient Occlusion

Test with Shadow

Second Test

Very cool, I do know some articles about how to implement the normal map, but it depends on the code you are using.

I don't know how to calculate them, but here is a nice article about that explains the difference of the maps quite well:

You must be registered to see the links

I've rad it a while ago and it made me understand the difference between them and when and for what to use which map.

Hey, thanks!! what do you mean, it depends on the code used

What are you trying to achieve with this?? or is it learning purposes?

Greetings, So what I'm trying to write is a fast raytracer that gives a good result.
If that is the case, will be published ..... if not not

THX, the Part with the Bump map, was helpfull !!!!

whoa, you got Ambient occlusion in?! that is something I have wanted to play with, at least with texture generation. what are you using for code? are you making custom shaders like open shader language, or are you coding in things raw like with C or something similar?

writen all in C#.....I don´t use Directx or Opengl....I load all Vertices, build the Trinagles....Genarate a world of Boxes to add vertices-Ids in it...for fast rendering....and the send the rays...

//Ambient Occlusion
float amount = 0.5f;
float end = 0.5f;
for (float xx = -end; xx <= end; xx+=amount)
{ for (float yy = -end; yy <= end; yy += amount)
{ for (float zz = -end; zz <= end; zz += amount)
{
Vector3 dir = NearestInersection.Normal + new Vector3(xx, yy, zz);
Ray aotray = new Ray((NearestInersection.Position + Vector3.Multiply(NearestInersection.Normal, 0.0000001f)), dir);
RenderPixel(new object[] { aotray, x, y, thread, RayOption.AO, NearestInersection, currentBound + 1 });
}
}
}

Awsome, very cool, I just might have to copy from you ;D
