we can now add colors to our vertices, but wouldn't it be cool if we could apply texture's to our vertices, and that way have texture blending?

Would be cool indeed!

How would you get the blend weight out? As vertex color channels? Then you'd have to limit the number of textures per vertex to a maximum of 5. (R,G,B,A, and 1-sum(R,G,B,A)).

[elementrix]

is this possible (adding texture's to vertices, just like vertex colors?) would be very cool to bring some life in terrains...

like this :


and ofcourse also blend them like vertex colors

I don't know how T. ed does it, but something like that would be cool. (and in deled then also usable on any object.)

together with the magnet you almost have a terrain editor

Yeah I can see that coming...specially with that cool i.e image

T.Ed uses Vertex Layers / Blending for Textures, same as DeleD would do in that case. (Most Terrain Editors working that way.)

[elementrix]

then it would be very cool to have , is it hard to implent (because they already have vertex coloring?)

I like the basic suggestion (i.e. improving terrain editing capabilities bij enabling texture blending), although extending DeleD's terrain editing capabilities is not a short term priority right now... Questions:

1) I don't see how your interface suggestion works. You manually want to select 5 different layers of textures for each vertex? So the next vertex could have different textures? And how do you set the blend factors? If you copied this of an existing solution, could you please point me towards it so I can figure out how that would work, because I am pretty stumped at this moment..

My suggestion for texture blending would be to extend existing material support to 5+ layers, and provide the user some interactive way of setting the belding weights between the 5 layers (i.e. a way of painting the terrain).

2) What file format would you export the terrain to? Besides collada, I don't think any of our current exported file formats actually supports weighted texture blending.

B3D supports weighted vertex-texturing.

[Basiror]

usually you have a paint tool where you apply blend weights in a per vertex basis and these weights are used to blend the texture layers together

On the other hand deled is not capable of efficient terrain editing
with more complex scenes its performance decreases immensly


just open your task manager select a complex mesh and move around

that must be a problem the way deled handles the mesh data internally


in order to achieve fast rendering results you need to store vertices in arrays

vertex,normal,color,texcoord0,texcoord1,....

I guess Deled uses display lists instead and rebuilds them with intermediate mode

[Paul-Jan]

Yep, but perhaps Elementrix was expecting something else?

Oh, and about the rendering speed... just to make a point here, in the whole 'rewriting DeleD to accomodate high poly and terrain modeling' process, the 'making the rendering a bit more efficient' part is not exactly the biggest hurdle to take... a 3D modeler does a fair bit more than just rendering some geometry. Rendering, selection and manipulation (all operations) will have to be gradually improved over time (as they will). Not a problem.
