What did you think about the lost world bullets?

Actually it seems there's a little highlight on the right half. I get this shade in Supermodel, in line with the arcade:

Just for comparison
this is how the model2 does specular
Yeah it does specular??

Well, as it seems, neither Model 3 is doing real specular. It fakes it elevating the angle of incidence value to some exponent. The actual formula could be re-written like this:

Code: Select all

float specularIntensity = pow(NdotL, pow(2.0, shininess + 3));

This is what happens if you don't normalize sun & vertex normals in vertex shader...

Speaking of which... It's my impression or the game runs way faster than the original ?

This is incredible work! The 3D engine is now very close to being perfect This weekend I need to sit down and hammer out the changes I've been working on. Might need to rewrite the ROM loading system one more time, too. I think we'll be able to decommission the legacy engine pretty soon -- can't see much of a reason for it to hang around, although I might let it stick around for just one more release as a fallback.
