Ventuz Forum

Getting some head way on understanding it. My issues is I don't see the input properties. How Do I expose the code values to the node properties?

Just by declaring global variables at the beginning of the code - those are then exposed.

Also you can use much of the Ventuz information such as lights, materials or textures. Look at the help page for the HLSL shader for some more info.

Hey,
I am playing around with the shader node and did a Mandelbrot Shader, fine so far...
I am wondering how to trigger the shader to kind of recalculate the graphics. When I am zooming in, resolution of the drawn graphics do get pretty bad...
Thanks!
Cheers,

Kind of dual-layer metallic shader - taken from ATI demo. Your geometry needs proper UV coordinates!

hey karol

very nice! THX

Hey!
find a simple Mandelbrot Shader attached... I like them a lot, really good ones look a lot better than mine .
Vza is done with the PLE.

Cheers,
Tobi

any plan to develop a velvet shader?

thank you.

Hi!

Could you post some sample images what you expect?

Trying to figure out an error in a shader.

error is:
"global variables cannot use the "half" type in ps_3_0. To treat this variable as a float use the backwards compatibilty flag"

this is the line of code getting the error.


QUAD_REAL2 QuadScreenSize : VIEWPORTPIXELSIZE <
string UIName="Screen Size";
string UIWidget="None";
>;

Do i just need to get the screen size in a different way. This is sample code that i am trying to use.

ok posted too soon, found a fix.

#define QUAD_REAL float
#define QUAD_REAL2 float2 //This was set to "half2" just had to set it to "float2"
#define QUAD_REAL3 half3
#define QUAD_REAL4 half4


This for a shadow from a single light point. Got the code to compiled right, now i have to figure out how to set up the ventuz scene and feed position data to the shader. This might take a while...
