Notably missing is:

This also updates a handful of files to use the new sh7091_bits.hpp.

I originally planned to make this a render-to-texture demo, but this
is fairly interesting by itself.

ta_parameter_format: generate TA parameter formats from csv

This replaces all handwritten TA parameter format structures with
automatically generated structures.
All valid TA parameter formats are now declared.

Also adds the incomplete modifier_volume example.
This also adds vec2 for UV coordinates, and obj_to_cpp has been
modified to parse vertex texture coordinates from obj files.

exceeded the previous value.

ta_fifo_polygon_converter: properly calculate ta_next_opb_offset
...
The main issue with the previous code:
constexpr uint32_t tiles = (640 / 32) * (320 / 32);
Should have been:
constexpr uint32_t tiles = (640 / 32) * (480 / 32);
The consequence of this is some OPBs were being overwritten by
TA_NEXT_OPB, causing corruption (missing triangles, incomplete
drawings) in some tiles.

font_outline_punch_through: implement punch through
...
This enables alpha blending for both font_outline and
font_outline_punch_through.
I have also experimented more with 16-gray vs 256-gray--I have not
decided which between monochrome, 16-gray, or 256-gray I like the
most.
Perhaps a better test might be to test hanzi.

ttf_outline: rectangular textures must include all bytes

Previously, the texture was truncated, which caused spurious pixels to
appear in the last row(s) of the texture.

font_*: fully parameterize source/destination bit depth

After implementing this, I realized I don't like the appearance of the
monochrome font as much as the antialiased font.

font_outline: remove all 1024/256/128 magic numbers
...
This fully threads both the real minimum size of the texture and the
dimensions of the texture through to the TA parameters.
This also removes spurious zero-area drawing commands (space
characters).
2023-12-22 23:54:39 +08:00
3b7e1eaef8
example: implement font_outline
...
This still needs to be cleaned up, particularly to properly pass the
texture size around--there are a few unnecessary '128x256' magic
numbers scattered in the code.

twiddle: fully parameterize texture twiddling function
...
I think the original version is more readable, but the newer version
is better overall because it doesn't require reading from dst, and is
able to directly write to a 32-bit dst.

This is very barebones, and uses the serial interface to communicate
the status of the "a" controller button being pressed.

This also adds ta_parameter_writer; I am not certain if I like this,
but it felt necessary to deal with ta_parameters being either 32 or 64
bytes long--for this reason, a reinterpret_cast to a union is less
attractive (the union members are not a fixed size).
