In Topic: Changing LoD on instancing and alpha testing

01 July 2013 - 09:48 AM

EDIT:

Thanks, it was something like this I needed smile.png

Your code makes sure, that values are included right away. Can't believe what a mess I ventured into with the other code (which I took over from a far-range fadeout of instancing with too little tthought).

 

Just for the record, the final shader code will look like this:

float l_dissolvemap_result = tex2D(g_dissolvemap_sampler, a_texcoord0).r;
if(g_alpha < l_dissolvemap_result)
    discard;

l_final_color.a = l_original_alpha;

In this way alpha-testing (or alpha-to-coverage, which is very similar, just with nicer edges and antialiasing) will still work for the original alpha of the object texture, as the g_alpha is not factored in.

Nice little program, that can create a normalmap from a texture. You simply input a texture and it will come with a suggestion for a normalmap, which you can adjust in all kinds of ways (intensity, noise removal, shape recognition, details of all levels). You will see a model with both texture and the new normalmap applied and you can see the alterations as you make them.

 

The program costs a little.

 

Nice tool for artists.

PIX for windows is used for knowing what is going on run-time in a DirectX-application. It can be used for a number of tasks, such as analyze, debug, optimize, and test programs that use Direct3D.

It can even grab assets loaded to the card, like textures, and it would be possible to rip a game of assets that way, if one was so inclined.

 

PIX comes with the DirectX-SDK.

Even when it is also a priced product, it has to be mentioned when talking about development tools, as it is - IMO - the best editor for 3D modelling. If you are working in a game developing team, I believe any artist would expect to be allowed to work in 3DSMax.

IncrediBuild is an amazing tool, that can speed up your compiling times immensely, if you are in a network of computers, like is the case in a workplace full of programmers. IncrediBuild will distribute the compiling out to a number of neighbouring machines and they will in parallel work together on the compilation.

 

Even if you are on a single machine, it should boost performance, as it takes full advantage of multicores, which your environment may not do.

 

I used it privately once upon a time when it was free, which it is not anymore - actually it is quite expensive (400-700$). I would highly recommend it for any company, that can afford it, as it cuts down compilation times significantly.
