Good work!

porcus

Will geometry shader also be available or not ?

My graphics card: Ati Radeon HD3850.
The while loop works well in glsl so I thought that this is caused by hlsl but
I will try it with enabled vsync.

porcus

No that has nothing to do with picking or terrains.

Hello,

I solved the problem with this code:

Code: Select all

int i = 0;
for(i=0;i<200;i++) {
if(NB.r < height){
height -= step;
offsetCoord += delta;
NB = tex2D(heightMap, offsetCoord);
}
}

It's a little bit slow (60 fps in hlsl instead of 300 in glsl) but it works so far.

Thanks for your reply, but I with this I get only a white
screen with the sand glass mouse pointer. The program crashes during the
hlsl compiler tries to compile it. I get no error messages.

During flight you have 4 forces which are affecting the airplane. (Lift, weight, thrust and drag) The lift vector is the normal vector of the wings. The weight vector is always pointing to the ground (it's NOT always the opposite of lift(only in straight and level flight)). The thrust vector is alwa...

This loop calculates the collision point between the ray from the eye and
a heightmap. And this is impossible without a loop.

porcus

Nothing of that works. There's no way to do this without a loop.
I've read on some other sites that the hlsl compiler tries to unroll
the loop and that's why it don't works. Is there any way to tell the
compiler that he shall not try to unroll it ?

Yes, I am using shader model 3.0

Hi, I tried to convert a glsl shader to hlsl. The most things are working but in one line a get a very strange error: HLSL pixel shader compilation failed: (54): error X3511: loop does not appear to terminate in a timely manner (1024 iterations) [...] while (NB.r < height) {<-----this is line 54 hei...

Could you tell me where changes are necessary that I can
do it on my own ?

Hi, I tried to use a tree with xeffects but the shadows are wrong. The alpha values of the leafes are ignored by xeffects although I set emt_alpha_channel_ref as materialtype. Here's a screenshot of the tree without Xeffects: http://img256.imageshack.us/img256/9403/schattenmitalphaaa.th.png Here's a...

Hi BlindSide,

I have some strange artifacts with ssao with your xeffects 1.1.
If I move the camera I get always black ugly stuff on the walls of the room.

Hello,

are there any modelling tools which are able to import the irrmesh
format or are there any plugins available for this ?
