int32_t CesiumGltf::AccessorSpec::bufferView = -1 |
The index of the bufferView.
The index of the buffer view. When undefined, the accessor MUST be initialized with zeros; sparse
property or extensions MAY override zeros with actual values.
Definition at line 73 of file AccessorSpec.h.
int64_t CesiumGltf::AccessorSpec::byteOffset = 0 |
The offset relative to the start of the buffer view in bytes.
This MUST be a multiple of the size of the component datatype. This property MUST NOT be defined when bufferView
is undefined.
Definition at line 81 of file AccessorSpec.h.
int32_t CesiumGltf::AccessorSpec::componentType = ComponentType::BYTE |
The datatype of the accessor's components.
Known values are defined in ComponentType.
UNSIGNED_INT type MUST NOT be used for any accessor that is not referenced by mesh.primitive.indices
.
Definition at line 92 of file AccessorSpec.h.
int64_t CesiumGltf::AccessorSpec::count = int64_t() |
The number of elements referenced by this accessor.
The number of elements referenced by this accessor, not to be confused with the number of bytes or number of components.
Definition at line 110 of file AccessorSpec.h.
std::vector<double> CesiumGltf::AccessorSpec::max |
Maximum value of each component in this accessor.
Array elements MUST be treated as having the same data type as accessor's componentType
. Both min
and max
arrays have the same length. The length is determined by the value of the type
property; it can be 1, 2, 3, 4, 9, or 16.
normalized
property has no effect on array values: they always correspond to the actual values stored in the buffer. When the accessor is sparse, this property MUST contain maximum values of accessor data with sparse substitution applied.
Definition at line 134 of file AccessorSpec.h.
std::vector<double> CesiumGltf::AccessorSpec::min |
Minimum value of each component in this accessor.
Array elements MUST be treated as having the same data type as accessor's componentType
. Both min
and max
arrays have the same length. The length is determined by the value of the type
property; it can be 1, 2, 3, 4, 9, or 16.
normalized
property has no effect on array values: they always correspond to the actual values stored in the buffer. When the accessor is sparse, this property MUST contain minimum values of accessor data with sparse substitution applied.
Definition at line 149 of file AccessorSpec.h.
bool CesiumGltf::AccessorSpec::normalized = false |
Specifies whether integer data values are normalized before usage.
Specifies whether integer data values are normalized (true
) to [0, 1] (for unsigned types) or to [-1, 1] (for signed types) when they are accessed. This property MUST NOT be set to true
for accessors with FLOAT
or UNSIGNED_INT
component type.
Definition at line 102 of file AccessorSpec.h.
std::string CesiumGltf::AccessorSpec::type = Type::SCALAR |
Specifies if the accessor's elements are scalars, vectors, or matrices.
Known values are defined in Type.
Definition at line 119 of file AccessorSpec.h.
