Flatten arrays of resources so each array element takes one binding number -fspv-print-all Print the SPIR-V module before each pass and after the last one. Useful for debugging SPIR-V legalization and optimization passes. -fspv-reduce-load-size Replaces loads of composite objects to reduce mem...
目录6.1 函数定义 6.1.1 函数调用惯例 6.1 函数定义 如上面的语法所示,有效着色器是一系列全局声明和函数定义。 声明一个函数,如下例所示: // prototype returnType functionName (type0 arg0, type1 arg1, ..., typen argn); 而函数定义如下: // definition returnType functionN...猜...
Specifies the byte offset between consecutive generic vertex attributes. If stride is 0, the generic vertex attributes are understood to be tightly packed in the array. The initial value is 0. pointer Specifies a offset of the first component of the first generic vertex attribute in the array i...
Array of scalars or vectors Each element has a base alignment equal to that of a vec4. Matrices Stored as a large array of column vectors, where each of those vectors has a base alignment of vec4. Struct Equal to the computed size of its elements according to the previous rules, but ...

Invalid qualifier on array - cannot make arrays of attribute or const variables Invalid qualifier on array in shader code, as demonstrated in the following: GLSL attribute float foo[2]; const float bar[1]; // const array of structs not allowed: struct S1 { int i; }; const S1 s1[3]...
floatarray[4];for(inti=0; i<4; i++){array[i]=0.0;} Statement Control flow GLSL supports standard C/C++ control flow, including: if-esle/switch-case for/while/do-while break/continue/return There is nogoto, usediscardto jump out. This statement is only valid under the fragment...
vec4 data2[arraySize + 2]; 这会使data2的size比常量值arraySize多2,无论常量值arraySize在shader被lower到可执行代码时的值为多少。 使用了特化常量所形成的表达式, 在shader中也会表现得好像一个特化常量,而不像一个常量。 arraySize + 2 // a specialization constant (with no constant_id) 此类表达式...
