include/nn/g3d/ModelObj.h line 20 at r1 (raw file):

    f32 unk;
    f32 radius;
};

I'm not sure of the member variable's meaning, but it's definitely four, not five.

The name is from the function call at 0xb1a2cc.

Suggestion:

struct Sphere {
    f32 x;
    f32 y;
    f32 z;
    f32 radius;
};

    void* _10;
    u8 _18;
    u8 m_ViewDependentModelFlags;

Where did you get that name from? I can't seem to find any usages.

include/nn/g3d/MaterialObj.h line 9 at r1 (raw file):

public:
    struct InitializeArgument {
        s32 CalculateMemorySize();

seems to just set some local variables

Suggestion:

void CalculateMemorySize();

include/nn/g3d/MaterialObj.h line 12 at r1 (raw file):

    };

    void Initialize(const InitializeArgument&, void*, u64);

Suggestion:

bool Initialize(const InitializeArgument&, void*, u64);

include/nn/g3d/MaterialObj.h line 14 at r1 (raw file):

    void Initialize(const InitializeArgument&, void*, u64);
    void InitializeDependPointer();
    void GetBlockBufferAlignment(gfx::TDevice<gfx::ApiVariationNvn8>*) const;

final change is SXTW X0, W8, which proves s64

Suggestion:

s64 GetBlockBufferAlignment(gfx::TDevice<gfx::ApiVariationNvn8>*) const;

    void InitializeDependPointer();
    void GetBlockBufferAlignment(gfx::TDevice<gfx::ApiVariationNvn8>*) const;
    void CalculateBlockBufferSize(gfx::TDevice<gfx::ApiVariationNvn8>*) const;

Suggestion:

s32 CalculateBlockBufferSize(gfx::TDevice<gfx::ApiVariationNvn8>*) const;

                          gfx::TMemoryPool<gfx::ApiVariationNvn8>*, s64, u64);

Suggestion:

    bool SetupBlockBuffer(gfx::TDevice<gfx::ApiVariationNvn8>*,
                          gfx::TMemoryPool<gfx::ApiVariationNvn8>*, s64, u64);
