I am using Environment mapping code and I found out it can not display on my friend PC (his VGA card is Geforce MX 440)... I wonder why this happen...Environment mapping is the most basic thing and I do not think that It can not be display...
---
Can anyone tell me why, or the Envi map in A6 only run on Geforce FX and other better VGA Card

even if it's basic, it's a shader and the 440 mx is just a bit newer version of the geforce 2, that doesn't support shaders yet.

yup, i think it would indeed be my VGA card (geforce 4 mx :P)
i think that's the problem why i cant display any shaders...

You can do Environment Mapping also with the Fixed Function Pipeline and so without a shader so you can draw it as well on a geforce 4 MX Even on my old Geforce 2 MX Environment Mapping can be draw realy fast.

XeXes, do you have a code example for this? I'm currently searching for a very fast environment mapping shader, but only code I've found were from ATI and that's a bit slow...


Cheers

Look in the Shader Index thread, Steempipe has offered one!

To Pappenheimer: Is this thread you mentioned
http://www.coniserver.net/ubbthreads/sho...part=2&vc=1
In this thread, steempipe give code for none pixel-shader-user, but he still use vertex shader and geforce MX 440 does not support this
--------
Can anyone tell me where to get this code...because to XeXeS, he still use env map only with Geforce 2

Thanks for your help

Here is the code for Environmentmapping with the Fixed Function Pipeline:

Code:

---

// Environmentmap
bmap EnvMap = <EnvMap+6.tga> // Bitmap with the environment Map

// Material
material matFFPEnvMapping
{
	// Skin zuweisen
	skin1 = EnvMap;
	
	// Effectcode
	effect = "
				
				// Textures
				texture mtlSkin1;
				
				// Technique
				technique EnvMapping01
				{
					pass pass01
					{
						// Setup textures
						Texture[0] = <mtlSkin1>;
						
						// Setup Texture Addressing
						AddressU[0] = Clamp;
						AddressV[0] = Clamp;
						
						// Setup Textureblending
						ColorArg1[0] = Texture;
						ColorOp[0] = SelectArg1;
						
						// How to use Texture coordinates
						TexCoordIndex[0] = CameraSpaceReflectionVector;
						TextureTransformFlags[0] = Count3;
					}
				}
				
				technique fallback {
					pass p0
					{
						
					}
				}
			";	
}

// Material
material matFFPEnvMappingWS
{
	// Skin zuweisen
	skin1 = EnvMap;
	
	// Effectcode
	effect = "
				
				// Textures
				texture mtlSkin1;
				texture entSkin1;
				
				// Technique
				technique EnvMapping01
				{
					pass pass01
					{
						// Setup textures
						Texture[0] = <mtlSkin1>;
						Texture[1] = <entSkin1>;
						
						// Setup Texture Addressing
						AddressU[0] = Clamp;
						AddressV[0] = Clamp;
						
						// Setup Textureblending
						ColorArg1[0] 	= Texture;
						ColorOp[0] 		= SelectArg1;
						ColorOp[1] 		= Modulate;
						ColorArg1[1]	= Current;
						ColorArg2[1]	= Texture;
						
						// How to use Texture coordinates
						TexCoordIndex[0] = CameraSpaceReflectionVector;
						TextureTransformFlags[0] = Count3;
					}
				}
				
				technique fallback {
					pass p0
					{
						
					}
				}
			";	
}

starter ConvertEnvMapToCubeMap
{
	bmap_to_cubemap(matFFPEnvMapping.skin1);
}

starter ConvertEnvMapToCubeMapWS
{
	bmap_to_cubemap(matFFPEnvMappingWS.skin1);
}

I've posted two materials:

The first one only uses the Environmentmap as Texture.
The second one uses the Environmentmap and the Entityskin as Texture ( Multitexturing ) so you can see both on the entity.

Have fun

Hello,

I have changed the code so you can adjust the value of the Reflection in Skill1 of the matieral:

Code:

---

material matFFPEnvMappingWS
{

// Skin zuweisen
skin1 	= EnvMap;

// Effectcode
effect = "
			// Textures
			texture mtlSkin1;
			texture entSkin1;
			
			// Variables
			DWORD mtlSkill1;
			
			// Technique
			technique EnvMapping01
			{
				pass pass01
				{
					// Setup textures
					Texture[0] = <mtlSkin1>;
					Texture[1] = <entSkin1>;

					// Setup Texture Addressing
					AddressU[0] = Clamp;
					AddressV[0] = Clamp;
					
					TextureFactor = <mtlSkill1>;
					
					// Setup Textureblending
					ColorArg1[0] 	= Texture;
					ColorOp[0] 		= Modulate;
					ColorArg2[0] 	= TFactor;
					ColorOp[1] 		= Add;
					ColorArg1[1]	= Current;
					ColorArg2[1]	= Texture;

					// How to use Texture coordinates
					TexCoordIndex[0] = CameraSpaceReflectionVector;
					TextureTransformFlags[0] = Count3;
				}
			}

			technique fallback 
			{
					pass p0
					{
					
					}
			}
		";
}

starter ConvertEnvMapToCubeMapWS
{
	bmap_to_cubemap(matFFPEnvMappingWS.skin1);
	matFFPEnvMappingWS.skill1 = pixel_for_vec(vector(30,30,30),100,8888);
}

I've not tested this code at all so I not gurantee that it works fine. Or that there are no errors.

Heaps of thanks XeXes!! I will try these codes as soon as possible... I was just wondering, I've downloaded the Aquamark 3 benchmark program some days ago, and they got this really cool 'masked environmental (reflection) mapping' on their model. This makes the submarine have a really nice metal/shiny look, but not the 'overdone' environmental mapping, which often produces a grey/silver/pink effect.
Anyway, first thing tomorrow, I'm gonna test your codes !

Edit: couldnt resist trying it out already! Works perfect and exactly the effect like in Aquamark3 !!! YEAHH!!! Thanks man!
Oww you forgot a ; at the end of bmap EnvMap = <EnvMap+6.tga> // Bitmap with the environment Map ...


Cheers
