| Implemented. |

| Version 1, 2018-8-8 |
| |
| Dependencies |
| |
| OpenGL ES 3.0 required. |
| |
| Overview |
| |
| This extension adds 3D texture support to the functionality |
| provided by the CHROMIUM_copy_texture extension. Two new |
| functions are exported, glCopyTexture3DANGLE and |
| glCopySubTexture3DANGLE that perform the same copy operations as |
| glCopyTextureCHROMIUM and glCopySubTextureCHROMIUM, respectively, |
| on GL_TEXTURE_3D and GL_TEXTURE_2D_ARRAY bound textures. |
| |
| New Procedures and Functions |
| |
| void CopyTexture3DANGLE(uint sourceId, |
| int sourceLevel, |
| enum destTarget, |
| uint destId, |
| int destLevel, |
| int internalFormat, |
| enum destType, |
| boolean unpackFlipY, |
| boolean unpackPremultiplyAlpha, |
| boolean unpackUnmultiplyAlpha) |
| |
| void CopySubTexture3DANGLE(uint sourceId, |
| int sourceLevel, |
| enum destTarget, |
| uint destId, |
| int destLevel, |
| int xoffset, |
| int yoffset, |
| int zoffset, |
| int x, |
| int y, |
| int z, |
| sizei width, |
| sizei height, |
| sizei depth, |
| boolean unpackFlipY, |
| boolean unpackPremultiplyAlpha, |
| boolean unpackUnmultiplyAlpha) |
| |
| Additions to the OpenGL ES 3.0 Specification |
| |
| The command |
| |
| CopyTexture3DANGLE |
| |
| All CopyTexture3DANGLE behavior is the same as |
| CopyTextureCHROMIUM unless otherwise defined below. |
| |
| When source texture doesn't contain a superset of the component |
| required by <internalFormat>, fill the components by the |
| following rules. |
| |
| source format color components |
| ---------------------------------------- |
| RED (R, 0, 0, 1) |
| RED_INTEGER (R, 0, 0, 1) |
| RG (R, G, 0, 1) |
| RG_INTEGER (R, G, 0, 1) |
| RGB (R, G, B, 1) |
| RGB_INTEGER (R, G, B, 1) |
| RGBA (R, G, B, A) |
| RGBA_INTEGER (R, G, B, A) |
| LUMINANCE_ALPHA (L, L, L, A) |
| LUMINANCE (L, L, L, 1) |
| ALPHA (0, 0, 0, A) |
| |
| INVALID_OPERATION is generated if the format of <sourceId> is not |
| one of formats in Table 1.1. |
| |
| INVALID_ENUM is generated if <destTarget> is not TEXTURE_3D or |
| TEXTURE_2D_ARRAY. |
| |
| INVALID_VALUE is generated if the texture corresponding to |
| <sourceId> has not been bound as <destTarget>. |
| |
| INVALID_OPERATION is generated if <internalFormat> is not one of |
| the sized internal formats in Table 1.0. |
| |
| The command |
| |
| CopySubTexture3DANGLE |
| |
| All CopySubTexture3DANGLE behavior is the same as |
| CopySubTextureCHROMIUM unless otherwise defined below. |
| |
| <zoffset> specifies a texel offset in the z direction |
| respectively within the destination texture. |
| |
| <z> specifies a texel offset in the z direction respectively |
| within the source texture. |
| |
| <depth> specifies the depth of the texture subimage. |
| |
| INVALID_ENUM is generated if <destTarget> is not TEXTURE_3D or |
| TEXTURE_2D_ARRAY. |
| |
| INVALID_VALUE is generated if the texture corresponding to |
| <sourceId> and <destId> have not been bound as <destTarget>. |
| |
| INVALID_VALUE is generated if either <sourceId> texture or |
| <destId> texture is not defined. |
| |
| INVALID_OPERATION is generated if the format of <sourceId> or |
| <destId> is not one of formats in Table 1.1. |
| |
| INVALID_VALUE is generated if zoffset is less than 0. |
| |
| INVALID_VALUE is generated if z is less than 0. |
| |
| INVALID_VALUE is generated if depth is less than 0. |
| |
| INVALID_VALUE is generated if (<z> + <depth>) > srcDepth. |
| |
| INVALID_VALUE is generated if (<zoffset> + <depth>) > destDepth. |
