degenerate triangle strip


#1

Looking at the MBX pdf from the SDK referencing the “golden” rules, we can read that using optimized triangle list could be sometimes more efficient than triangle strip however do we have a benefit to use degenerate triangle strip, adding more vertices to the data but keeping just 1 call ? Wondering if we should use degenerate triangle strip or ordered triangle indexed list…

Iyes,

 

Adding degenerate polygons is a better solution if the total number of extra polygons is not very high and your application is not bandwidth limited (which might be your case). We recommend triangle list because is more generic optimisation and it also works well with our current generation of hardware.
