So, Jonathan, what you're saying is you basically take the union of what you want to output and what is requested, and provide that?

Iop::build_handles() loops through each input calling build_handles(), then it does the same on all local Knobs. If the Knob is a 2D knob then it doesn't draw when transform_mode is 3D. /*! Sets viewer to 3D mode. */ /*virtual*/ void build_handles(ViewerContext* ctx) { Matrix4 saved_matrix = ctx->modelmatrix; int saved_mode = ctx->transform_mode(); if (saved_mode == VIEWER_2D) { // If modelmatrix has had a projection applied to it, // skip drawing this renderer's 3D scene: if (ctx->modelmatrix.a32 != 0.0f) return; // Get matrices up to date and switch to 3D mode: validate(false); ctx->modelmatrix *= get_format_matrix(0, 0); ctx->modelmatrix *= projection_matrix(0); ctx->modelmatrix *= camera_matrix(0); ctx->transform_mode(VIEWER_PERSP); } Iop::build_handles(ctx); // Restore ctx state: ctx->modelmatrix = saved_matrix; ctx->transform_mode(saved_mode); } Good luck, -jonathan On Oct 31, 2011, at 1:30 AM, Chishing Yip wrote: > Hi Johnathan, > > I tried set transform_mode() & ViewerContext::model_matrix ( also tried > proj_matrix ) but still got the weird axis, is there any pseudo code please? > > Thanks a lot, > Shing > > On Sat, Oct 29, 2011 at 12:12 AM, Chishing Yip <[email protected]> wrote: > Will have a try later, thanks again! > > > On Sat, Oct 29, 2011 at 12:05 AM, Jonathan Egstad <[email protected]> > wrote: > Yes, plus setting the ViewContext's transform_mode() for each input/knob. > > > On Oct 28, 2011, at 8:30 AM, Chishing Yip wrote: > >> Hi Jonathan, >> >> Thanks a lot for you reply. >> For the camera transform, do you mean the ViewerContext ( OpenGL ) >> model/projection matrix? >> >> Shing >> >> On Fri, Oct 28, 2011 at 10:47 PM, Jonathan Egstad <[email protected]> >> wrote: >> For mixed transform Ops you must implement your own build_handles() to set >> the viewer mode correctly for each input or knob.
