/**
|
||||
* @file z_viscvg.c
|
||||
*
|
||||
* This file implements full-screen frame buffer effects involving the visualization of Coverage in various ways.
|
||||
*
|
||||
* Coverage is roughly how much of a pixel is covered by a primitive; the final coverage for a frame is stored in the
|
||||
* color image alpha component where it is used for antialiasing, see PreRender.c and §15 of the programming manual for
|
||||
* details.
|
||||
*
|
||||
* To understand this file, it is helpful to remember that A_MEM is essentially synonymous with coverage, and that
|
||||
* `GBL_c1/2(p, a, m, b)` usually represents the RDP blender calculation `(p * a + m * b)`.
|
||||
* Note the division step that is often included in the blender calculation is omitted; the division is skipped if
|
||||
* force blending (FORCE_BL) is set, which is the case for all render modes used in this file.
|
||||
*
|
||||
* Coverage is full when not on an edge, while on an edge it is usually lower. Since coverage is treated as an alpha
|
||||
* value, edges of primitives where coverage is lower will show up darker than primitive interiors in all of the
|
||||
* available modes.
|
||||
*
|
||||
* Coverage is abbreviated to "cvg"; "FB RGB" ("framebuffer red/green/blue") is the color the pixel originally had
|
||||
* before the filter is applied.

/**

* @file z_viszbuf.c
|
||||
*
|
||||
* This file implements a full-screen framebuffer effect for visualizing the z-buffer (AKA depth buffer), using either
|
||||
* cycling RGBA or a single fading color.
|
||||
*
|
||||
* This is done by reading the z-buffer as if it were a color image, the format of which is specified by the selected
|
||||
* vis type:
|
||||
* - VIS_ZBUF_TYPE_IA : Produces a monotonic fade from primColor to envColor as depth increases.
|
||||
* - VIS_ZBUF_TYPE_RGBA : Produces vibrant almost-periodic-looking bands.
|
||||
*
|
||||
* In both cases this occurs because of the format the depth information takes: it is 18-bit, and is a nonnegative
|
||||
* floating-point number with
|
||||
* bbb mmmmmmmmmmm dd|dd
|
||||
* exponent mantissa dz value (only first 16 bits visible to CPU, the least significant 2 bits of dz are ignored)
|
||||
*
|
||||
* Reading z-buffer as IA16:
|
||||
* bbbmmmmm mmmmmmdd
|
||||
* iiiiiiii aaaaaaaa
|
||||
*
|
||||
* Since floating-point numbers of this format have the same ordering as their binary/hex representation, increasing
|
||||
* the depth also increases the intensity in the IA16 representation and hence the interpolation parameter used to
|
||||
* combine primColor and envColor. The alpha is ignored by the RenderMode.
|
||||
*
|
||||
* Reading z-buffer as RGBA16:
|
||||
* bbbmm mmmmm mmmmd d
|
||||
* rrrrr ggggg bbbbb a
|
||||
*
|
||||
* The red increases monotonically with the depth. The significant visible oscillation is the green component, because
|
||||
* it rolls over every time the second-most-significant bit of the mantissa increments. The blue component oscillates
|
||||
* too rapidly to be particularly visible (it rolls over when the 7th-most-significant bit increments). The alpha is
|
||||
* again ignored by the RenderMode.
