Summary	0024268: Wrong triangulation on the boundaries of the cones
Description	Some shapes included cones have triangulation problems. It seems that it caused by integration of branch CR23650_2. Different images are on the current master: http://occt-tests/IR-2013-10-17-IR-2013-10-17-occt/Debian60-64/diff-Debian60-64.html http://occt-tests/IR-2013-10-17-IR-2013-10-17-occt/Windows-32-VC9/diff-Windows-32-VC9.html IMAGE bugs vis bug22188: bug22188_Driver1_Viewer1_View1.png differs IMAGE bugs vis bug22900: bug22900_Driver1_Viewer1_View1.png differs IMAGE bugs mesh bug23512_1: bug23512_1_Driver1_Viewer1_View1.png differs IMAGE bugs modalg_2 bug22818_1: bug22818_1_Driver1_Viewer1_View1.png differs IMAGE bugs modalg_2 bug22818_2: bug22818_2_Driver1_Viewer1_View1.png differs IMAGE bugs modalg_2 bug22818_3: bug22818_3_Driver1_Viewer1_View1.png differs IMAGE bugs modalg_2 bug22818_4: bug22818_4_Driver1_Viewer1_View1.png differs IMAGE bugs modalg_5 bug23282_1: bug23282_1_Driver1_Viewer1_View1.png differs IMAGE bugs modalg_5 bug23282_2: bug23282_2_Driver1_Viewer1_View1.png differs IMAGE mesh standard_shading L1: L1.png differs IMAGE mesh standard_shading O5: O5.png differs IMAGE mesh standard_shading A7: A7.png differs

In attached files results of tests. bugs vis bug22188 - improvements in normals computing, without CR23650_2 and this branch we can see that some normals are wrong. I can't see any problems in this case. bugs vis bug22900 - fixed, see attach. bugs mesh bug23512_1 - fixed, see attach. bugs modalg_2 bug22818_1 - can't see differences in images. bugs modalg_2 bug22818_2 - can't see differences in images. bugs modalg_2 bug22818_3 - fixed, see attach. bugs modalg_2 bug22818_4 - fixed, see attach. bugs modalg_5 bug23282_1 - fixed, see attach. bugs modalg_5 bug23282_2 - fixed, see attach. mesh standard_shading L1 - improvements in normals computing, see attach. mesh standard_shading O5 - same "bugs vis bug22188" message. mesh standard_shading A7 - fixed, see attach.
