In-house game engine

[mant]

Hi, this is the first time I show something interesting on Irrlicht forum.
Here is the video of an in-house engine that I've developed for 6 months using Irrlicht 1.8.4 and other open-source libraries.

Images are clipped by the forum, open in a new window to see in full size:
First cube rendered (physically based rendering - PBR)


One of the level for AI testing (single point light)


Render test (all materials are PBR, random point lights)


New GUI skin


Sponza scene after corrected some lighting (differrent from the video), 3 directional lights


New feature to render transparent objects with/without normal map (this version is released yesterday)


Sponza scene with transparency support


Development:
- Irrlicht itself is not modified at all, but compiled with 8 material textures support enabled
- UI is done with CEGUI
- I write custom deferred renderer using Irrlicht as back-end
- Still don't have reflection due to lack of cubemap support, could someone help me to understand Screen Space Reflection using ray marching?
- May study XEffects to implement shadow for this engine
- Will probably modify Irrlicht for more performance
- Open-source? Maybe, but not soon for sure, I have to finish my first game, demo scenes can be released if I make some

CubeMap support is in Irrlicht trunk version I think (was coded by Nadro, I didn't get yet to use it, but slight warning - the interface might change once more for that within next months).

Great screenshots!

I will try to allocate time to check out trunk version so maybe I could understand the implementation of cubemap and contribute it to 1.9
No promises but I will do something to contribute

Your transparent cubes look odd: only the front faces are showing, probably because you have back-face culling still on. You might want to disable that when you have transparent materials.
Your random point lights test looks cool.

Then he'll need one more pass of deferred for one more layer of transparency.

I have just realized that, I could also blend Irrlicht's forward pass with mine, or the base material of transparent cube is currently solid, it should not be solid.
I will check again, thanks guys.

Good lord!, there are more models out there than the (in)famous Sponza atrium by crytek!

[CuteAlien]

Hehe, everyone uses Sponza. I guess it allows for great comparisons with other people using it. Btw, Sponza atrium shows even up in game of thrones :-) (for King's Landing castle).

Sponza just works for me in first try so I keep using it, will look for other scenes when I have enough time and motivation for that

Hi Mant,

That is a nice normalmap on that lion's head.
I am having a few problems with normalmaps which is how I came across your post.
Nice work though.

Thank you, it's original normal map image from Crytek's sponza. And my pixel shader code is:

Code: Select all

 
vec3 normalMap() {
  vec3 Normal = normalize(normal);
  vec3 Tangent = normalize(tangent);
  Tangent = normalize(Tangent - dot(Tangent, Normal) * Normal);
  vec3 Bitangent = cross(Tangent, Normal);
  vec3 Bump = texture(texture1, texCoord).xyz;
  Bump = 2.0 * Bump - vec3(1.0, 1.0, 1.0);
  mat3 TBN = mat3(Tangent, Bitangent, Normal);
  Normal = TBN * Bump;
  Normal = normalize(Normal);
  return Normal;
}
 

Hope it will help you a little!
