Revising Mesh Type 2 (Discussion)

[Airikita]

I'm currently revising mesh header type 2 from the wiki:

http://wiki.spinout182.com/w/Maps_and_Scenes#Mesh_Header

 

It doesn't seem like it was given a proper look-over, as I am comparing data with the map of Kokiri Forest, and the ordering actually appears to be:

 

a and c = X and Z position of first display list (using rendering distance)
b and d = X and Z position of second display list (using rendering distance)

 

More appropriately: a and b = X positions, c and d = Z positions.

 

NOT "a and b, c and d", because I used an actor to position the hex of the Twin's House:

046E 00AE 025B 0133 03008ED8 00000000

 

0x046E = 1134

0x025B = 603

 

I also noted that type 2 mesh DOES NOT use distance. In fact, based on a position I used, everything rendered when Link was FACING that position... NOT when Link was at a certain distance.

 

Result of observation:

 

 

This is useful for building large maps, and can help a ton for those making high-quality 3D maps. Mesh types 0 and 1 are not good in terms of this.

 

It also seems as though the ground is connected to a central path component:

02C0 0132 00AF 0A0A 03004860 03018048

 

My guess is that when there's 2 display lists connected, they share rendering together, and will render together based on either x and z positions. But I have not tested this.

I would also look at other maps as well including Hyrule field. When I was doing music research, I was shocked to find several differences between types of maps and the location of the values and their significance.

Hyrule Field would be something I would look at... especially considering the behavior of the ground is odd for Mesh type 2, considering how it works.

Though that could be a condition in the DList that keeps the ground from disappearing.

 

I believe there was the same scenario when I looked at Hyrule Field though... the pathway was in the same line as the ground DList.

I could experiment with my Kokiri Forest modded map, and see if connecting the water with the ground would do anything significant.
