(171206) +o In lmcolor mode, Nurbs were being rendered incorrectly. This is fixed. (172421) +o Material changes per vertex were sometimes being processed incorrectly for primitives such as Tmeshes, Qstrips, etc.. This resulted in bad visual artifacts. This is fixed. (177466) +o Many lmcolor bugs have been fixed to ensure correctness and good performance. (egs. 145400) +o Many two-sided lighting bugs have been fixed to ensure correct behavior.

This had caused a bus error when called from certain applications. (181333) +o Changes were made to prevent floating point exception in ________ggggllllNNNNppppttttSSSSmmmmooooooootttthhhhRRRRGGGGBBBBLLLLiiiinnnneeee____aaaassssmmmm. (184033) +o A problem was fixed with bbbblllleeeennnnddddffffuuuunnnnccccttttiiiioooonnnn((((BBBBFFFF____SSSSAAAA,,,, BBBBFFFF____MMMMSSSSAAAA)))).

This has been fixed. +o The tolerance for NURBS knot values was changed to 10.0e-6. +o _g_l__x__d_e_v was renamed _g_l__d_e_v since it no longer contains any X development products. +o On RealityEngine systems, a rectcopy call could corrupt the z-buffer. This has been fixed. +o Several problems with multi-headed RealityEngine and SkyWriter systems on MP-bus systems were fixed. +o On Onyx RealityEngine systems, certain conditions caused the message Bad CP command encountered to be printed on the console. This has been made much less likely to occur due to errors in hardware. Errors in user programs may still cause this message to be printed. +o Frequent calls to dither caused the video output of RealityEngine systems to shift. This has been fixed. +o Picking of polygons was broken on 5.0.1 RealityEngine systems. This has been fixed. +o The Distributed Graphics Library (DGL) was broken in 5.0.1. This has been fixed, but you should look at the discussion in Chapter 5 of these release notes. +o A problem where texgen and ``old-style'' polygons could crash graphics on RealityEngine systems was fixed. +o Returned z-buffer values obtained from lrectread had bytes swapped on RealityEngine systems. This has been fixed. +o PAL mode on the composite video output of RealityEngine systems was not working. It now works. +o Calls to lrectread and lrectwrite of exactly 2048 pixels wide could hang VGX graphics. This has been - 17 - fixed. 4.7 _B_u_g__F_i_x_e_s__B_e_t_w_e_e_n__I_R_I_X__5_._0__a_n_d__5_._0_._1 +o Double buffering in an overlay window of a _G_L_X_D_r_a_w widget now works. The only constraints are that the overlay GL window must have a main framebuffer GL window associated with it, for example: GGGGLLLLXXXXccccoooonnnnffffiiiigggg rrrrggggbbbb____oooovvvv[[[[]]]] ==== {{{{ {{{{ GGGGLLLLXXXX____NNNNOOOORRRRMMMMAAAALLLL,,,, GGGGLLLLXXXX____RRRRGGGGBBBB,,,, TTTTRRRRUUUUEEEE}}}} ,,,, {{{{ GGGGLLLLXXXX____OOOOVVVVEEEERRRRLLLLAAAAYYYY,,,, GGGGLLLLXXXX____BBBBUUUUFFFFSSSSIIIIZZZZEEEE,,,, 4444}}}} ,,,, {{{{ GGGGLLLLXXXX____OOOOVVVVEEEERRRRLLLLAAAAYYYY,,,, GGGGLLLLXXXX____DDDDOOOOUUUUBBBBLLLLEEEE,,,, TTTTRRRRUUUUEEEE}}}} ,,,, {{{{ 0000,,,, 0000,,,, 0000}}}} }}}};;;; and the overlay GL window will be clipped to the main framebuffer GL window's extents. +o New RealityEngine features are now supported by _g_l_d_e_b_u_g: constants for texdef2d and glcompat, and support for texdef3d. +o _g_l_d_e_b_u_g no longer requires the _D_I_S_P_L_A_Y environment variable to be set. +o Graphics programs using the Distributed Graphics Library (DGL) no longer have errors when mixing connection types (_D_G_L_L_O_C_A_L vs. _D_G_L_T_S_O_C_K_E_T). +o Calls to lrectwrite with the pixmode PM_STRIDE parameter set with more than 511 lines caused a kernel panic. This has been fixed. +o The ARCS PROM now handles different screen resolutions. +o Overlay planes now work in mixed model, double-buffered applications. +o The GL routine afunction now works on RealityEngine systems. +o On RealityEngine, The behavior of swapbuffers could be unpredictable with many calls to winset and drawmode(OVERDRAW). This is now fixed. +o Several problems related to lighting when using shademodel(FLAT) or two-sided lighting have been fixed on RealityEngine. - 18 - 4.8 _B_u_g__F_i_x_e_s__B_e_t_w_e_e_n__4_._0_._5__a_n_d__5_._0 4.8.1 _R_e_a_l_i_t_y_E_n_g_i_n_e_,__R_e_a_l_i_t_y_E_n_g_i_n_e_2_,__a_n_d__V_T_X +o pixmode use combined with rectcopy to/from the z-buffer no longer hangs the pipe. +o Multiple GL programs doing lrectwrites no longer hang the pipe. +o PM_ADD24, PM_RTOL, PM_ZDATA, and PM_BTOT now work correctly. +o readdisplay is no longer off by one pixel. +o Moving multi-sampling GL windows now copies all bits. +o GL underlays are more robust. +o pupdraw menus draw faster. +o The overlay visual now works, including double-buffered overlays. +o Picking and feedback are much more robust. +o IL ilchain no longer displays wrong data. +o Combining GL windows using texturing with GL windows using fog no longer hangs the pipe. +o texgen no longer forgets its parameters when texturing is turned off. +o DGL now supports new texdef and tevdef options. +o 1600x1200_60 video format should now always produce stable video. +o /_u_s_r/_g_f_x/_s_e_t_m_o_n -_s now sets sync correctly. +o 960x680_60 cursor position is now correct. +o On dual-head RealityEngine systems, changing video formats on the fly now works correctly. +o On dual-head RealityEngine systems, the cursor tracks correctly on the second head even if it is running a different format from the first head. - 19 - +o Mixed-model GL programs can now use GLX_RGBSIZE correctly. +o Multisampling combined with blendcolor sometimes blended incorrectly. +o PYM_HOLLOW and PYM_SHRINK now work correctly. +o Color index values are now clamped correctly. +o Depthcueing now works correctly in all cases. +o setlinestyle now does not hang the pipe. +o On dual-head systems, getgdesc now gives correct answers before winopen. Using DGL, double-precision GL calls no longer fail. +o On VGX and RealityEngine systems, nurbs are more reliable. +o Using lrectwrite over DGL, pixmode variants are more reliable. +o gversion before a call to _f_o_r_k works correctly.
