Hello, I began using 3DVIA studio. I have some few questions I coudn't find the answers anyelsewhere.
Does 3DVIA Studio support floating textures, cubemaps and tex3D and what are thoses types and how to access it?
What is the equivalent in 3DVIA studio of virtools BB ->
VR Distrib Add/Remove
Combine in RT View
Render Scene in RT View
Thank you by advance!
What do you mean by floating textures?
Cubemaps are supported by the default blinn/phong shaders of Studio -- you simply map them to the "Reflection" parameter of the material.
Not sure on tex3D, not a shader expert -- you can learn more about Shaders in Studio here: http://www.3dvia.com/studio/documentation/user-manual/shaders (be sure to use the side nav for more info)... not sure if it will answer your question though 
In terms of the building blocks... it's been too long since I used Virtools, I can't remember exactly what they do. Judging by the names, did they have something to do with rendering a camera view to texture? If so, "Render to Texture" is the BB you may be looking for, and it's description can be found here: http://www.3dvia.com/studio/documentation/building-blocks/viewport/rendering/render-to-texture
Hello! About floating texture, I mean Texture which have floats instead of the classical ints as values. Is there a type like this in 3DVia Studio or a way to create it?
About the Render to Texture BB, it's the same idea but not quite the same options. You could have the option of rendering with a shader, and with that you could have multiple Textures as outputs. Is that stille possible? Anyway, i'll look the info you gave to me.
And for VR Distrib Add/Remove, it's a BB for sending data to parts of a cluster (slaves) . Does 3DVIA studio have cluster managing yet?
Thanks
3DVIA Studio Pro's latest version has Cluster Management.
I don't normally see or hear anyone doing point translations of images, so I will let another member of the community or a dev answer that one
Hi,
About textures: yes, 3DVIA does support floating textures, cubemaps and volumetric textures (3D).
The way you can access it and create it really depends on what you want to do with it (use an existing texture ? dynamic creation as a render target ? dynamic creation as a parametric texture ?).
If you just want to import an existing texture, then just drag & drop the file inside Studio project using .dds fileformat properly formated.
- For floating textures, then you will be able to directly take advantage of HDR values activating HDR mode in the viewport, or read custom floating values inside custom shader, etc...
- For cubemaps, as said Iain if you drag & drop a .dds cube map then you could directly use it as cube reflection texture, or also as Ambiant Light IBL map for instance. You could have floating cube maps for HDR IBL (check Libraries / Presets / Lights / Hangar IBL Light sample)
- For 3D texture, I think it also work to drag & drop it as .dds (never tester though). But I don't think we deliver a ready to use 3D texture shader, so you may need to write it.
If you need to create those textures dynamically, then it depends on what you want to do ?
Example for creating a RenderTexture (texture to be used as target of a viewport) in VSL:
- Floating:
vkRenderTexturePtr texture = vkRenderTexture::CreateInstance();
texture.SetObjectID("float");
texture.Setup(map_size_x, map_size_y, 1, ePF_128_FLOAT_RGBA, vkRenderTexture::fRt2D);
then use it as target texture for a given viewport (vkViewport::SetTexture)
- Cubemap:
vkRenderTexturePtr texture = vkRenderTexture::CreateInstance();
texture.SetObjectID("floatTexture");
texture.Setup(map_size_x, map_size_y, 1, ePF_24_RGB_888, vkRenderTexture::fRtCube);
Then only way to fill a CubeMap in VSL is to create 6 viewports that each will render inside a cube face using index param of CreateInstance method:
vkViewport viewportFace01 = vkViewport::CreateInstance(texture, null, vkIRect(0, 0, map_size_x, map_size_y), 0);
vkViewport viewportFace02 = vkViewport::CreateInstance(texture, null, vkIRect(0, 0, map_size_x, map_size_y), 1);
...
vkImage::CreateCubeMap() is not bound in VSL, so you must use SDK if you really want to "manually" fill cube maps pixels without using viewport rendering.
- Volume:
vkRenderTexturePtr texture = vkRenderTexture::CreateInstance();
texture.SetObjectID("VolumeTexture");
texture.Setup(map_size_x, map_size_y, 1, ePF_24_RGB_888, vkRenderTexture::fRtVolume);
I don't think you could fill these texture using VSL, so this code is probably not usable..
vkImage::CreateVolume() is not bound in VSL, so you must use SDK if you really want to create a volume texture dynamically.
Hope it helps, I try to post a sample soon,
Cheers,
Arnaud.
Thanks a lot, that's lot a of good informations.
Basicallt I would like to use OpenCL (not OpenGL!) with the 3DVIA textures....I don't know really if it is possible or how to begin. Do you think it is possible?
Edit: Some more informations, I just want to fil my textures using OpenCL.
PS : I have the pro version.
You must log in to post.
