rendered splines

[Iain Denby]

Just created a space frame using renderable splines. My rendering now really slows down. Do they take longer to render than, say, cylinders (used the create the same shape) ?

i'd create a space frame from a triangular extrusion, i think its classed as prism in viz/max and then use the lattice modifier with ignore hiden edges unchecked. You can control the no. of sections to the frame from the no. of divisions etc. of the original geometry and the thickness of the frame from the lattice controls

An alternative method of modeling wasn't really my question. But thanks anyway.

[jucaro]

have already collapsed your renderable splines to a mesh or a poly?

[Iain Denby]

No I haven't. Do you think that will make a difference?

[JamesTaylor]

I suggested the alternative method as i think that renderable splines are known to be slow when rendering...?? think i'm correct in that... The alternative method may well help speed your rendering back up

I don't think a different modeling method will change anything, unless it allows you to create a more polygon efficient model. You can do it with rendered splines, but just make sure when you give them a rendered thickness, that you control the number of sides (4 - 6 if you are just building a frame), don't leave it on something rediculously high, or your polygon count will shoot through the roof as you multiply your frame.

 

And in any case that would only slow down your rendering as it builds the mesh and loads it into memory pre-render. It shouldn't slow down vray.... it's been proven many times that vray can plow through heavy polygon scenes.....as long as your computer has the memory to manage the geometry.

 

So the answer is no, making it with splines shouldn't slow down the render, with the exception of load time after you hit render before vray actually kicks in. And unless this is a huge space frame.... you probably won't even notice that part.

 

(as mentioned before collapsing your geometry will help)
