Pi3d: Can I change the pivot point of an ImageSprite? - Raspberry Pi Forums

hi all,

have following simplified code create image sprite in pi3d library:

code: select all

file_texture = pi3d.texture("texture.png", blend=true) image_sprite = pi3d.imagesprite(texture=file_texture, shader=uv_flatshader, w=1024, h=1024) image_sprite.position(0, 0, 0)

in application rotate image with:

code: select all

image_sprite.rotatetoz(value)

works fine. rotate image on specific pivot point / center point, need create image symmetrical in size around center point. save “unused” texture memory want adjust center point different location on texture sprite. there native way adjust center-point coordinates in pi3d? or need rotate , calculate new sprite.position achieve this?

i think need calculate on-the-fly, i'm prepared stand corrected if 2d object handled in same way 3d 1 0 points set in stone when object created.
however, it's not big job calculation in 2d 0 points follow arc determined size of image.
real picture , put in on table. rotate around it's center while follow bottom left corner. follow circle radius of it's center it's corner (pythagoras), not massive calculation.
