A raytracer written in C++ that embeds Lua to assemble scenes to be traced.

iris's Issues

Blue component of object's diffuse color isn't being rendered.

An (1.0, 0.0, 1.0) diffuse color is being interpreted as an (1.0, 0.0, 0.0) diffuse color.

Possible causes:

• Logic error when parsing Lua files.
• Logic error when storing configuration data in C++.

Possible tests:

• Check if the configuration files are being parsed correctly.
• Check if the configuration data is being stored in the C++ data structures correctly.
• Check if the problem extends for other materials.

The scene isn't rendered for large enough images (Currently known limitation: 400x 400px)

For some test values like 250x200 and 250x250 the program executed without crashing but did not generate any final image.

Possible causes:

• Poor bitmap converting.
• Hardware can't handle that many samples (256) per that many pixels.

Possible tests:

• Integrate FreeImage to the project and try exporting to different file formats.
• Test on better hardware.
• Decrease the number of samples.
