; Math constants for rotation.
|

;
|
||||
; To compute X * cos(theta), start by converting theta (0-27) into a table base
|
||||
; address (using the 28-byte tables RotIndexLo_cos / RotIndexHi_cos). Split the
|
||||
; X coordinate into nibbles, use the low 4 bits to index into the adjusted
|
||||
; RotTabLo pointer, and the high 4 bits to index into the adjusted RotTabHi
|
||||
; pointer. Add the values at those locations together.
|
||||
;
|
||||
; This is similar to the way the scale table works. See ScaleTableLo, below,
|
||||
; for a longer explanation of how the nibbles are used.
|
||||
;
|
||||
; As an example, suppose we have a point at (36,56), and we want to rotate it 90
|
||||
; degrees (rot=7). We use the RotIndex tables to get the table base addresses:
|
||||
; sin=$00/$00 ($1200/$1300), cos=$70/$07 ($1270/$1307). We split the
|
||||
; coordinates into nibbles without shifting ($24,$38 --> $20 $04, $30 $08), and
|
||||
; use the nibbles as indexes into the tables:
|
||||
;
|
||||
; X * cos(theta) = ($1274)+($1327) = $00+$00 = 0
|
||||
; Y * sin(theta) = ($1208)+($1330) = $08+$30 = 56
|
||||
; X * sin(theta) = ($1204)+($1320) = $04+$20 = 36
|
||||
; Y * cos(theta) = ($1278)+($1337) = $00+$00 = 0
|
||||
;
|
||||
; XC = X*cos(theta) - Y*sin(theta) = -56
|
||||
; YC = X*sin(theta) + Y*cos(theta) = 36
|
||||
;
|
||||
; which is exactly what we expected (counter-clockwise).
|
||||
;
|
||||
; The largest value from the index table is $EE, so that last 17 bytes in each
|
||||
; table are unused.

; Math constants for scaling.
|
||||
;
|
||||
; Each table has 16 sets of 16 entries, with one set for each of the 16 possible
|
||||
; scale values. The values within a set determine how one 4-bit nibble of the
|
||||
; coordinate is scaled.
|
||||
;
|
||||
; Suppose you want to scale the value 100 ($64) by scale factor 8 (a bit over
|
||||
; half size). We begin by using self-modifying code to select the table
|
||||
; subsets. This is done in a clever way to avoid shifting. The instructions
|
||||
; that load from ScaleTabLo are modified to reference $1800, $1810, $1820, and
|
||||
; so on. The instructions that load from ScaleTabHi reference $1900, $1901,
|
||||
; $1902, etc. The offset comes from the two 16-byte ScaleIndex tables. For a
|
||||
; scale factor of 8, we'll be using $1880 and $1908 as the base addresses.
|
||||
;
|
||||
; To do the actual scaling, we mask to get the low part of the value ($04) and
|
||||
; index into ScaleTabLo, at address $1884. We mask the high part of the value
|
||||
; ($60) and index into ScaleTabHi, at $1968. We add the values there ($02, $36)
|
||||
; to get $38 = 56, which is just over half size as expected.
|
||||
;
|
||||
; This is an approximation, but so is any integer division, and it's done in
|
||||
; 512+32=544 bytes instead of the 16*256=4096 bytes that you'd need for a fully-
|
||||
; formed scale. For hi-res graphics it's certainly good enough.
