Hi guys, does anybody now how to model a polygon that always looks at the user, this would be for some nice cones on the appron and I have a very limited polygon budget in my project so far....Can it be accomplished via gmax-BLGC or is this one of the Scasm things. Thanks...

SCASM command is RotateToAircraft and the BGLC command I can't remember now :), I'll look it up when I get home this evening...Arno

Thank You, as always, Arno, BTW where do you get so much info? Is it by your personnal experience, or do you have a hidden and secret source? :-)

Right now it is personal experience :), but I learned most of it from reading the SCASM docs and then just trying if it does what I want it to do. For the BGLC commands I use the Scenery SDK normally (or I search through the include files).Arno

Hi Gabriel,You asked nothing new so I wont tell anything new :) Anyway, I just made a quick search through older posts:http://ftp.avsim.com/dcforum/DCForumID10/1804.htmlhttp://ftp.avsim.com/cgi-bin/dcforum/dcboa...rum=DCForumID10Hope this will help somehow. Details as usually will come from Arno or RhumbaFlappy... (and of course from somebody else is possible to!) :)Regards,Goran BrumenFS Slovenija 2002 teamhttp://slovenia.avsim.net

Thanks Guys, going to try that at home....

Hi Gabriel...Here's a 'RotateToAircraft' API macro I call using Apt26 to make a statue which always faces the observer (aircraft). For best display efficiency, it uses a DXT1 type bitmap. 'ShadedTexPoly(' is used here because the 3D object is a photoreal statue to be illuminated at night and allows the code to be a little more simple than havingto create a 'YourTexture_LM.bmp' for night illumination. For trees or other objects not intended to be illuminated at night, you may use the standard 'TexPoly(' opcode below, instead of 'Shaded'TexPoly. ;**********************************Area( 5 %1 %2 %3 )IfVarRange( :no_display 346 %12 4 ) PerspectiveCall( :_P0 ) Jump( : ):_P0; Perspective:R0 mif( %11 ) RefPoint( 2 :R1 %4 %1 %2 v1= %10 E= %11 %13 %14 ) melse RefPoint( 7 :R1 %4 %1 %2 v1= %10 %13 %14 ) mifend:R1 RotateToAircraft( :R2 0 0 0 0 0 1 0 0 0 ) Return :R2Points( 0 -2 0 0 ; 0 -2 8 0 ; 1 3 8 0 ; 2 3 0 0 ; 3) LoadBitmap( 0 6 e0 0 0 0 YourBitmap.bmp )ShadedTexPoly( ai 0 95 251 1 95 63 2 2 63 3 2 251 )Return:no_displayEndA'********************************************Here's a picture of the object:J.R.
