per pixel phong material

[needforhint]

get it here:http://www.medeal.sk/irr/phongPERpixel.zip (have to see it in move)

here is a per pixel shader doing a phong effect, during trying to set right call back constants I discovered bad behaviors of irrlicht world,view and projection matrices...so main.cpp is in if anyone had such trouble (compiled on irrlicht 0.14), the pixel and vertex shaders are 2.0 so only ATI 9X00 and higher and GeForce(some good one)



by the way, per pixel spot light is on the way

Nice work

Btw youre gonna have touble implementing that spotlight since the cjeapest way to do it is via cube maps(which are not suppourted by irrlicht)


what u do is get a cube map which is black except a circle on one of the sides

Multiply it by the color of the light then the base texture

the texcoord of the cube maps is composed of three vectors not 2 therefore u can use the light source as the texcoord of the cube map

thanks,

I have a question for u omaremad, have you ever implemented 2 textures into a shader with irrlicht?
[SOLVED: YES , CAN]

[omaremad]

did u use a shader call back with integers sent by the sampler 2d names

i never used 2 texture in hlsl i only used it in my HDR glsl

I didnt set texture in callback. Both, layer 1 and layer 2 texture were automaticly mapped into hlsl, I used sampler2d definition-.
