3.70 beta 33 |
Task Description
Files of exactly 4k length can cause a full crash exception when opened.

14 | Texture/Material/Finish | Definite Bug | 3.70 beta 32 | Very Low | Medium | coincident transparency issue | Closed | |
3.70 beta 33 |
Task Description
Overlapping partially transparent objects can result in speckled shadows. Rays shouldn’t leak through the coincident areas, they should return one of the two textures. This was correct in 3.6.
#declare testmat = material { texture {
pigment {color <1,0,0> transmit 0.5}
}};
camera { location <1.0, 2.0, -4.0>
direction 1.5*z
right x*image_width/image_height
look_at <1.0, -0.2, 0.0>
angle 30 }
light_source {<-10, 10, -5> color rgb <1, 1, 1>}
plane {y,-1 pigment{rgb <1,1,1>}}
union {
sphere {<0.0,0,0>,0.5 material{testmat}}
sphere {<0.1,0,0>,0.5 material{testmat}}
sphere {<0.2,0,0>,0.5 material{testmat}}
sphere {<0.3,0,0>,0.5 material{testmat}}

3.70 beta 33 |
Task Description
Using trace or inside with a julia fractal causes a crash.
#declare Test = julia_fractal {

quaternion
cube
max_iteration 8
precision 20
};
#declare Norm = <0,0,0>;

3.70 beta 33 |
Task Description
Reflective texture maps can cause a stack overflow crash.
sphere{0,1

[1 pigment{rgb 0} finish{reflection 1}]
}
}

18 | Distribution | Compatibility Issue | 3.70 beta 32 | Very Low | Medium | read only files in distribution | Closed | |
3.70 beta 33 |
Task Description
Array.inc and subsurface.pov are in read only mode, they probably should have normal permissions.
|
|
31 | Texture/Material/Finish | Definite Bug | 3.70 beta 32 | Very Low | Medium | function pattern in image map | Closed | |
3.70 beta 33 |
Task Description
Function use in image maps is broken.
The following should result in a white and green checkered unit square, but is transparent.
camera {
location <0.0, 0.5, -4.0>
direction 1.5*z
right x*image_width/image_height
look_at <0.0, 0.0, 0.0>
}
background {rgb <1,1,1>}
light_source {

color rgb <1, 1, 1>
}
plane {y,-1 pigment{checker rgb <1,0,0> rgb <1,0.5,0.5> }}
plane {y,-0.99
pigment {

32 | Other | Definite Bug | 3.70 beta 32 | Very Low | Medium | tiff file extention error | Closed | |
|
Task Description
The parser is failing to read the .tiff file extension from the input string...
bump_map { tiff "earth03_hf2.tiff" }
Results in file not found, but
bump_map { tiff "earth03_hf2" }
will find the file. It might be that it’s not a three character extension?

53 | Geometric Primitives | Definite Bug | 3.70 beta 32 | Very Low | Medium | Blob trace level | Closed | |
|
Task Description
It appears that reflective bounces from blobs are not incrementing the trace level, causing self- reflecting hall of mirror portions to stall renders.

17 | Texture/Material/Finish | Possible Bug | 3.70 beta 32 | Very Low | Low | square blotches in transparency | Closed | |
3.70 beta 33 |
Task Description
There can be square (32×32) blotches in partially transparent objects.
global_settings {

Task Description
Adding an AOI pattern is asked for fairly frequently.

33 | Parser/SDL | Definite Bug | 3.70 beta 32 | Very Low | Low | parse accepting invalid vector float components | Closed | |
3.70 beta 33 |
Task Description
The parser is missing extra period characters when it parses a float as a vector component.
#local sample = <0.0.0.1,0,0>;
Doesn’t generate an error, but should.

|
69 | Other | Compatibility Issue | Not applicable | Very Low | Low | #version fails to raise error | Closed | |
|
Task Description
Scenes starting with the incorrect syntax
version 3.7;
do not raise an error, instead they render a black screen with an empty scene warning. #version should fail with an error when the # is missing.

|
12 | Texture/Material/Finish | Definite Bug | 3.70 beta 32 | Very Low | Very Low | facets pattern in normal map | Closed | |
3.70 RC6 |
Task Description
Using a facet pattern in a normal map results in a unspecified error in Evaluate_TPat at the render stage. This probably should be caught at parse time to give a more descriptive error and a line number.
Example:
sphere {
0, 1
texture{
pigment{rgb <1,1,1>}
normal {
facets
normal_map {
[0 bumps ]
[0.5 facets ]
[1 bumps ]
}
}
}
}

28 | Frontend | Feature Request | 3.70 beta 32 | Very Low | Low | #debug message not displayed. | Tracked on GitHub | |
Future release |
Task Description
The #debug message stream is only being flushed when it hits a newline character, instead of after each #debug statement. This means that some final strings don’t show up.
#debug "This line prints,\n but this line doesn't."

71 | User interface | Unimp. Feature/TODO | 3.70 beta 34 | Very Low | Low | raise warning when command line option has no effect | Tracked on GitHub | |
|
Task Description
Warnings should be raised when a command line option has no effect, for example...
pvengine +am
is legal, but without the number after it, it has no effect.
pvengine +am7
should be an error, and also raises no warnings.

|
20 | User interface | Feature Request | 3.70 beta 32 | Very Low | Very Low | render window behavior | Tracked on GitHub | |
|
Task Description
When changing the behavior of the render window, “Keep above main”, requires restarting the POV editor to take effect. It would be nice either to get a warning to restart, or to get it to work without restarting.
