GXSetTevDirect

• Category: Indirect Texturing
• Matrix Status: Implemented
• Matrix Notes: Parity-checked wrapper that disables indirect effects for a TEV stage via canonical GXSetTevIndirect(...) direct settings.
• Matrix Link: Gfx-GX-API-Matrix

Official SDK (Reference)

• Manual page: reference/man/gfx/gx/Indirect/GXSetTevDirect.html
• SDK source: reference/gx/GXBump.c (GXSetTevDirect, around lines 371+)
• Verified SDK behavior:
  • GXSetTevDirect(tev_stage) is a convenience call that forwards to:
    • ind_stage = GX_INDTEXSTAGE0
    • format = GX_ITF_8
    • bias_sel = GX_ITB_NONE
    • matrix_sel = GX_ITM_OFF
    • wrap_s/t = GX_ITW_OFF
    • add_prev = FALSE
    • utc_lod = FALSE
    • alpha_sel = GX_ITBA_OFF
  • Uses CHECK_IN_BGN semantics (inherited by forwarded call path).

libPorpoise Implementation

• Runtime implementation area: src/gx
• Public API surface: include/dolphin/gx
• Current implementation:
  • src/gx/pc_gx.c: GXSetTevDirect forwards to GXSetTevIndirect with the same canonical constants as SDK.
  • Begin-safe behavior is inherited through GXSetTevIndirect (which now flushes pending begin state before update).

SDK vs Porpoise Diff

• Signature parity:
  • SDK: void GXSetTevDirect(GXTevStageID tev_stage)
  • Porpoise: same
• Behavioral parity:
  • SDK and Porpoise both implement this as the canonical direct-mode wrapper over GXSetTevIndirect.
• Known divergence:
  • None in wrapper semantics.

Validation Checklist

• GX demo coverage checked (wrapper path)
• Pikmin usage path checked (TEV direct path)
• Matrix status updated if needed
• Notes updated with concrete file/function references

Working Notes

• Build sanity target after update: pikmin_demo (Win32 Debug).
