[Source, Library, Sample] Parallel Split Shadow Mapping that you can re-USE

[nicolas]

And this VB6 user is still hunting for shadow mapping in VB6...

[Toaster]

PSSM is camera based so you cant just render it once and then stop updating it. You dont have to render it every loop though.

Acually this I noticed that this methos is really slow since we use the Tv3ds render function 4 times each update. Is this even faster then stencilshadows? Coz I get like 1 sec spike each time and yes I have frustum culling active and it's the renderfunction that takes all the fps.

Something that I missed?

[tedlin01]

What is the splits for? Why do we split 4 times each frame and is it possible to change some setting so that we just split once?

[Toaster]

Thats what PSSM does. It splits 4 shadow maps down the view frustum so you get higher shadow quality. If you want standard shadow mapping you'll have to write your own shader. There is plenty of info around on this. Check out the XNA shadow mapping sample.

how can i use this with my trees and landscape? i've tried implementing it and the result was that all of my trees and land are white. then as the light position moves the black areas move and cover the white areas. i don't see any shadows, and why does my objects become white/black?

[Mietze]

Try projecting your shadow map onto the geometry only - without any depth testing - to see if the projection is correct. If not, have fun with matrices. If it is, check the depth testing. You may want to implement alpha tested shadows on your trees (only). But thats up to you and very easy to do with a single line.

How to hook the geometry in vb.net??

Code:

            // Hook up our geometry rendering
            ParallelSplitShadowMapping.RenderGeometry += RenderShadowCasters;

[Rbn_3D]

Please anyone knows the way to make the Invoke in Vb.net??

[WEst]

Try

Code:

AddHandler ParallelSplitShadowMapping.RenderGeometry, AddressOf RenderShadowCasters

[Rbn_3D]

Try

Code:

AddHandler ParallelSplitShadowMapping.RenderGeometry, AddressOf RenderShadowCasters

Not works, it says "'RenderGeometry' is not a event of 'eStudioz.PSSM.CParallelSplitShadowMapping'

I try

Code:

"AddHandler PSSM.CParallelSplitShadowMapping.RenderGeometryDelegate, AddressOf RGHook"

, but not works, It says RenderGeometryDelegate is not a event of...

I tried this too:

Code:

Dim RG As New PSSM.CParallelSplitShadowMapping.RenderGeometryDelegate(AddressOf RGHook)

And it no says error, but I don't know what do after...

I know it´s not specially hard, but I'm confused,  Please help...

[Gamecode]

have recored this source code into vb.net ?

[Lil`Buh]

mmm cant get the sample to work...

all i get is a grey background and a white rectangle no teapots no floor no shadows

nothing in the debug file

i just commented all the eStudioz.Input.dll references bcause i get an error "file version" of tv3d dll

any help ?

[bbence]

Does this dll still work?
Reason I'm asking is that when I put the necessary engine object assignments in my VB.net code, it complains about the required dll version for truevision (which is older then the current one).

[Mietze]

Hm.. well, the source code of the dll is included, so why just dont link it against the newest truevision dll and recompile this assembly? Or what about including the classes directly in your project?

I'm using VB.net. But I will download C# express and try to compile with it.

[bbence]

Okay, it works, sort of...

Now all my meshes become greyscale.

Any ideas why? Thanks!

Hm, it doesn't work.
I doesn't matter if I render the meshes or not in the invoked method, I get the greyscale effect every time. Seems like I'm missing something.
Maybe I shouldn't use managed lighting?

[Mietze]

Hm.. have you tried debugging the depth map by rendering it onto your screen as I do here?

The grayscale stuff can be either to a wrong depth test (everything is in shadow) or to a wrong lightnin system.
