hello

i have a question about texturing in Gem.
when i use an rvb bitmap, jpg or tif, for texturing for example a simple square, i have less colors in gem than expected.
indeed, it is awfully degraded, looking like 256 colors bitmap.

is it an usual thing or not ?

thank you

what object you use for texturing ? there is two method, it could help.

i have already notice some color reduction as i run the system in 16 bit, it is not like 8 bit colors, but a little reduced, maybe turning your desktop in 32 bit could ehance the quality (but not the fps).

hello
i used pix_image then pix_texture then square.
i have not yet discovered a lot in gem, so if there is another method, i would be very happy to know it...

my desktop is in 32 bits.
the gradations are very noisy and steppy, but indeed, it could look like 16 bits.
so maybe it is a material problem (bad screen or bad video card) and not something inside gem. i will try to test it soon on another computer.

other simple tests with coloured spheres, for example, without texture, don't show this problem : from shadow to light, the sphere look is not degraded.

from recent experience,
these texture things seems to really depend of the graphic you use, maybe it having something to do with memory or the openGl capabilities of the card.
