| Summary | 0023049: Optimize packaging and dependencies of visualization libraries | ||||
| Description | Currently, there are two known issues related to undesirable dependencies of OCCT libraries related to visualization: 1. TKernel depends on Xlib due to OSD_FontMgr class. This issue was reported by the community a year ago: http://www.opencascade.org/org/forum/thread_20042/ Potential solution: move this class to TKV3d or TKOpenGl (TKV3d is also considered because some customers use OSD_FontMgr as a part of OCCT public API in their applications), the final decision is pending. 2. TKService depends on FreeImage library (remark by SZV). This dependency is yet to be analyzed. 3. TKOpenGl depends on FTGL+FreeType2 libraries for text rendering functionality. FTGL library is not updated since '08 whilst has frozen RC slice for a long time, has known bugs and uses outdated OpenGL techniques for rendering (no VBO possible, no GL3.0 compatibility, unsafe FreeType2 library initialization, no advanced scalable options possible etc.). Moreover the only small part of provided functionality is used by OCCT. So this is suggested to implement own font rendering functionality based on Freetype2 library directly and eliminate FTGL dependency. 4. TKOpenGl depends on FreeImagePlus library for printing functionality on Windows platform. It seems redundant dependency that should be removed in future. | ||||

Hi all, I haven't tested it - but could this be a replacement for FTGL: http://code.google.com/p/freetype-gl/ Best regards. Patrik |

|
Correction of #23196 introduces direct dependency of TKOpenGl on FreeType library. However, this does not look critical as TKOpenGl already depends on FTGL library that also requires FreeType. |
|
|
p.3 from the initial description (dependency on FTGL) is resolved by the patch for 0023457 |
|
|
p.1 is resolved within 0023242 issue (OSD_FontMgr was moved to TKService as Font_FontMgr). |
|
|
p.1 0023415 removes Xlib dependencies from TKernel. |
|
|
Problem p.2 is cancelled, TKService (Font package) now accumulates various algorithms related to font support based on FreeType. Thus only p.4 remains. |
|
|
Please switch to "verified" - the dependency from C++ library FreeImagePlus (not C library FreeImage) has been eliminated within patch for 0027763 |
