SURenderingOptionsGetValue function throw exception

[lik]

I am using SDK_Win_x64_18-0-18664.zip. I want to get the default front face color and back face color. The code in vs2017:

1. int main() {

2. SUInitialize();
   

3. SUModelRef model = SU_INVALID;
   

4. SUResult res = SUModelCreateFromFile(&model, "model.skp");
   

5. if (res != SU_ERROR_NONE)
   

6.     return 1;
   

7. SURenderingOptionsRef ro;
   

8. SUModelGetRenderingOptions(model, &ro);
   

9. SUTypedValueRef value;
   

10. SUTypedValueCreate(&value);
    

11. res = SURenderingOptionsGetValue(ro, "FaceFrontColor", &value);
    

12. SUColor color;
    

13. SUTypedValueGetColor(value, &color);
    

14. SUTypedValueRelease(&value);
    

15. ...
    

16. }
    when run the row 11 throw exception, as fallow:
    

I has checked this is not the utf8 coding problem.
I think this maybe the sdk’s bug. Has anybody ever had this question?

SUModelGetRenderingOptions(model, &ro);

Are you checking the return value?

I can’t get the return value, it has crashed.

I was referring to row 8, GetRenderingOptions

It may be that you need to call SUSceneGetUseRenderingOptions
Refer to this link: Getting Rendering Options DisplayColorByLayer

Thanks for your replies.

I have tried SUSceneGetUseRenderingOptions and SUSceneGetRenderingOptions, it has the same problem.

I pasted in your code, it was failing on SUTypedValueCreate because the passed value was not initially set, so try this…

SUTypedValueRef value = SU_INVALID;
