### Buffering-camera projection path from static Terrain analysis
|

|
||||
A further headless-IDA review of the same GOG `Terrain.dll` identifies a
|
||||
concrete `CBufferingCamera` implementation path without requiring a live game
|
||||
process. Its method at RVA `0x4D740` copies exactly 64 bytes (16 dwords) into
|
||||
the component at offset `+0x10`. Its frame-preparation method at RVA `0x4D9C0`
|
||||
queries a viewport rectangle through a virtual method at `+0x3C`, derives its
|
||||
`CBufferingCamera`-related implementation path without requiring a live game
|
||||
process. The procedure at RVA `0x4D740` copies exactly 64 bytes (16 dwords)
|
||||
into its receiver at offset `+0x10`. The frame-preparation procedure at RVA
|
||||
`0x4D9C0` queries a viewport rectangle through a virtual method at `+0x3C`, derives its
|
||||
width, height, centre and an aspect ratio from that rectangle, and obtains
|
||||
projection data through the camera interface. Projection type `0` uses a
|
||||
component float at offset `+0x234` as an angle passed to `tan(angle / 2)`;
|
||||
receiver float at offset `+0x234` as an angle passed to `tan(angle / 2)`;
|
||||
projection type `2` obtains a five-float block through a virtual method at
|
||||
`+0x70`. Any other non-zero type raises `Not supported projection type`.

Live read-only evidence now confirms the relocation-aware global contract. In
|

one elevated GOG run, `Terrain.dll` loaded at `0x02510000`; its global at
|

`base + 0x7355C` held non-null `0x0B37DF08`, whose first dword was
|
||||
`0x025765B4` — exactly the relocated `off_100665B4` vtable from the
|
||||
`LoadCamera` construction path. This proves the global is a live camera object
|
||||
with that outer vtable. It also corrects an overreach: raw reads at global
|
||||
offsets `+0x10` and `+0x234` did not yield a finite 4×4 matrix and a projection
|
||||
angle in this sample. The static procedures' receiver and the exported global
|
||||
pointer are therefore not yet proven to have the same adjustment/layout; those
|
||||
offsets must remain unassigned until the selector/interface relationship is
|
||||
recovered.

Live elevated read-only probe впервые подтвердил relocation-aware runtime связь:
|

`Terrain.dll` был загружен по `0x02510000`, global `base + 0x7355C` содержал
|

non-null `0x0B37DF08`, а первый dword этого объекта был `0x025765B4` — ровно

live camera object с outer vtable, но одновременно исправляет прежнее слишком

сильное сопоставление offsets: raw read `global + 0x10` не дал finite 4x4 matrix,
|

а `+0x234` был zero в данном sample. Receiver static procedures `0x4D740`/
|
||||
`0x4D9C0` и exported global ещё не доказаны как один layout без interface

adjustment; их offsets остаются unassigned до recovery selector relationship.

Локальная IDA-база уточняет адреса этой связи: `stdGetCurrentCamera2` — это
