Hello,
I need to create a lot of basic objects at runtime, in 3D, so I need to "group" (combine) objects to reduce the draw-calls.
Is there any native function in GLBasic to do that? Or is there someone who was able to create such function?
Thank you for help!
You can either combine them with the modeling program. You can write such a combiner with the X_GETFACE commands.
Thank you, but I need to combine objects at runtime.
QuoteYou can write such a combiner with the X_GETFACE commands.
It means there is no built-in function to make this?
Ok, thank you!
There's no real way of grouping vertex or poly objects but you can merge the creation process by calling X_OBJSTART only once for the new object id, and then add parts to it.
For example, for a kitchen table model (psuedo) from five part to one like Ikea;
open a new vertex object for a table, no merge
merge the table top vertex object, with merge
merge the four legs vertex object, with merge
close the table vertex object
:rtfm:
FUNCTION make_object: obj AS vertex_object, object_merge
IF object_merge THEN X_OBJSTART obj.num
X_OBJADDVERTEX ...
...
X_OBJNEWGROUP
IF object_merge THEN X_OBJEND
ENDFUNCTION
