#Targa+…resolution

I would like to configure my Targa+ to display a higher resolution than 512×486…at least 640×480, or 800×600….more important however, I would like to be able to do video capture (using Tips+) at the higher resolutions for use in 3d Studio. Can someone help with this? Thanks in advance! Tag Grossman 73417,2322

for video capture you pretty well stuck with the ntsc res.(512×486 or 756×486) and thats 32 bit 16 bit for the targa 64+. 32 bit for 756×486 if your running an atvista 4meg. and of course thats interlaced. if just want to display your targa images at higher res then use tmode to set up your targa to go as high as 1024x768x16 non-interlaced. but you will not be able to record to ntsc at that level, i'm getting very good results with my targa 64 at 512x486x32 bit , why the need for higher res? sherwood

if you need higher res maps in 3ds you might try this . first capture the scene you want in tips at 512x486x32 then save it as a xxxxxx.win . then bring it back in after you have reset the targa to a higher res mode say 1024×768 then you could paste the image in the upper left of the screen then keep bringing it into tips but each time flip the image so that its sides match the previous image. this should take 4 win files of the first saved image. what you get is a high res map that is good for reflection maping on objects. after you do this then go back into 3ds and load the original targa image you captured in the back ground and create a sphere then create a texture with the new high res map and apply it to the sphere you don't need to map it on the sphere because its a reflection map. but make sure that when you create the texture you use 100 per shinyness and specular is also white. what you get is a very realistic looking chrome ball and if you animate the camera around it it will be a very nice effect. you could of also done this to the sphere with the original image also because its a sphere and reflection mapping works best with round objects. but if you have an object that is not round the high rez one will work well compared to the original on. anyway i'm wearing out my keyboard…. hope this helps… sherwood

Teodor, Depends on what model Targa+ you have. The Targa+ 16/32 and 64 will capture up to 756x486x16-bit. Use the TMODE utility to set the mode, and run TIPS+ (which supports all the resolutions). Kevin Krell – Computer Support Associates

Is your camera's resolution greater than 512 lines horizontal? If it isn't, then the sharpness of your grabs won't improve when you capture at 640 x 480 or 756 x 486. The physical dimensions of the image grab in pixels will be greater though.
